Once again… the classic argument of: “Well, I grew up using this system, and I’m used to the system. I have built an internal intuition for how hot and cold the temperature is. I am used to >100 being hot! 40 is not hot!”
Well then. I grew up using celcius and… “IT’S FOURTY FUCKING ONE DEGREES OUTSIDE?” sounds just as hot.
By that metric, kelvin would be even better though.
Please raise this temperature by 1.4x10^-23 Joules - statements of the utterly deranged
And Rankine would be even better than Kelvin in terms of “big number go brrr.” Water boils at 671 R.
Of course, Rankine is the most obnoxious unit I’ve ever had to deal with, but those numbers sure are big!
You mean it’s THREE HUNDRED AND FOURTEEN FUCKING DEGREES OUTSIDE?!
You miss out on screaming that it’s negative anything though.
-40F = -40C
Kelvin doesn’t have a negative.
You can absolutely yell about that. And when Fahrenheit flips to negative, you’re ready to express some big feelings about how fucking cold it is.
The best system would have 0 at a mild, comfortable temperature, and go up or down by 100 degrees per one degrees Fahrenheit.
But mild and comfortable is different for different people who are acclimated to different weather.
We need a defined ‘mild’ temperature. i vote for 70F/21C.
It’s a bit chilly for the warm weathered folks and a bit warm for the cold weathered folks. Seems reasonable but I’m open to suggestions.I’d adjust it to 68/20 just so it lines up with whole numbers in both systems. And on second thought, make it 90 per degree Fahrenheit so any whole F or C value can convert to a whole number.
As a cold weathered folk, I can confirm that 70 is my upper limit for nice temperature
0 for freezing because water falls from the fucking sky.
by that metric
Americans cannot understand any metric
In point of fact Americans have gotten impressive results out of far more complicated metrics than metric. It’s not a matter of understanding, it’s a matter of pride. And of not having to buy all new tools.
2 liter bottle.
Checkmate, athiests.
Also we have electric, water and gas meters smh
This is why I say ‘metre’ for the measure and ‘meter’ for the measurement device
And Demeter for the harvest
9mm
We’re more familiar with 5.56x45mm thanks to all our school shootings thank you very much.
In the same way a US ton and a metric ton is like 10% different, a 556 bullet is actually 5.7 mm across.
Because the minor diameter of the barrel is 5.56 mm and the major diameter is 5.69 mm. If the bullet were smaller than that then the propellant would blow past it. They didn’t make a 'murican millimetre like they did with the imperial system.
I would make a bet that more mass shootings are done with 9mm. Depending on which shootings they consider ‘mass’ I see estimates from 60-80% for handgun usage. I’m sure the cheap .22 is a large number, but 9mm is probably right up there. There is a large bias in reporting the school shootings and shootings involving rifles by the media. They almost ignore the others.
28 grams to an ounce
OK, but with Rankine, if it’s 101 out, you can go Five Hundred and SIXTY degrees??!
“Kelvin” sounds a lot like “communism” you pinko
Fahrenheit is better because 69 is a nice temperature
Celsius is better because 69 is very hot
Yes but we all know you will never experience that 69 (and I think you know it too)
What? Never been in a sauna? Do it, it’s really nice!
You do experience 69°C if you go to sauna before it’s warm
Meh… Give it another couple of decades.
Fahrenheit is best for ambient temperatures. 0 F is what humans feel is a very cold day, and 100 F is what humans feel is a very hot day.
Celsius is best for literally everything else, but for humans feeling of ambient temperature Fahrenheit is best
only if you grow up with fahrenheit.
Um. No.
If I said a movie was a 7/10, you would understand what that means because it’s a scale. You don’t have to “grow up” using a 0-10 scale to understand it.
Like if I asked you to rate something on a scale of 4-17, you’d understand what I mean. The numbers are different but the concept of a scale remains the same.
if I knew that you are a european and you told me a movie was 5/10, i would assume it was average. if i knew you were American, i would assume it was dogshit.
Americans have a weird relationship with numbers.
also, as mentioned in another post: if 0 is too cold and 100 is too hot, surely 50 would be a pleasant temperature?
Dear god, is Fahrenheit the reason behind meaningless movie ratings? Another reason to hate it…
“Americans” ah, I see. You don’t actually care about effective systems of measurement, you just want to shit on people that are different from you.
Also, as answered in another post: Why would you assume that humans, an endothermic species, prefers exactly 50% thermal energy? Of course we sit around the 70F region, we’re warm-blooded mammals. We don’t want to be half cold, we want to be mostly warm.
No matter how much you complain or argue, it’s never going to be true that Celsius is the one-and-only most perfect system of temperature measurement. The fact is that both systems have their applications, as any intelligent member of the scientific community would tell you.
Get over it.
considering america is the only place that uses it, i can’t really find any other factor to use.
the point of a temperature scale is to quantify temperature as to ease its communication. if one player is using a different scale that’s just complicating things.
also, if its an “intuitive” scale, surely it should take human bias into account?
Really not. Basically, you just need to peg feelings to a number, just like you are doing.
Celsius:
below -20 = deadly even with good gear, you can’t spend long here
-15 = very dangerous / deadly
-10 = starting to get dangerous
-5 = starting to get uncomfortable
0 = very cold
5 = cold
10 = a little cold 15 = cool
20 = nice
25 = warm
30 = hot
35 = starting to get uncomfortable
40 = starting to get dangerous
45 = very dangerous / deadly
50+ = deadly even with good gear, you can’t spend long hereI don’t think you understand what I said.
Also, that’s a lot of explaining, and lots of feelings associated with arbitrary numbers. Fahrenheit doesn’t need anywhere near that level of explanation. It doesn’t necessitate the pegging of feelings to random numbers.
The sentence “Fahrenheit is a 0-100 scale of how hot it is outside” is all anyone needs to immediately understand and be able to use fahrenheit. I didn’t need to type out a long list of what each temperature value means to me. There is no need for a mneumonic such as “10 is cold, 20s not, 30s warm, and 40s hot”
If you’re doing math in a lab, absolutely use Celsius. I’m not saying it doesn’t have a place. It’s just not the be-all end-all most perfectest temperature measurement system ever.
I think you are projecting your feeling onto others; I don’t have “a mneumonic” in my head. That was for your benefit, since you are not immersed in that scale.
When I see the weather report and it says tomorrow it is going to be 25 degrees with light wind, I know that it will be a pleasant day. The same way I know what the reporter is saying, I have been immersed in the English language since birth, it requires no though to understand the words they are saying.
It requires no thought to understand that 25 degrees and light wind is a nice day. It just is.
I don’t have that intuitive sense for the F scale, I always have to convert it to a sensible number. I know 100 is around 37, which is really hot.
But it requires you to be familiar with an arbitrary -20 - 40 scale. Which makes way less sense than a 0-100 scale.
I don’t need to use the mnemonic either, I grew up in the U.S. so I understand both systems perfectly well. But the mnemonic exists because Celsius uses an inherently less sensible scale. You only understand it internally because you grew up with it. A person who grew up with neither system would find fahrenheit easier to understand from an unbiased position because it’s more logical.
deg C is no more arbitrary than deg F; any more than French is more arbitrary than English.
It is a strange argument to say “You only understand it internally because you grew up with it.”; well yes, but that is exactly the same with the deg F scale.
A person who grew up with neither system would find fahrenheit easier to understand from an unbiased position because it’s more logical.
In your opinion.
In my opinion it is far more logical to base you temperature scale on repeatable physical measurements, than say what a person feels.
0 C = water freezes
0 F =Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt)
100 C = water boils
100 F = best estimate for average human body temperature.The F scale is not built on logic.
fahrenheit doesn’t exist if you use celsius i guess??
It doesn’t, because celsius users doesn’t think about fahrenheit at all.
So you’re saying that 0 and 100 aren’t intuitively obvious? I find that really strange when it’s doing a better job keeping to base 10 than the metric system in this particular use case.
They aren’t. And fahrenheit is not a 0-100 scale. It is just the scale you picked out of it in order to make some kind of sense out of the non-intuitive system which it is.
For Celsius, 0 is freezing cold and 100 is boiling hot - that’s intuitive too.
I have literally never felt 0°F in my life and couldn’t tell you how cold it is, just that it’s very cold. I believe everyone has a rough understanding how 0°C and 100°C feel though.
It is intuitive, and that’s fine. Having the same intuition around human comfort zones is also fine. One measurement system can’t really cover everything.
People tend not to want to live in places where it’s routinely under 0F or over 100F. You’ll tolerate it, but you won’t like it. It’s a very natural range of human comfort.
No, they’re not. I couldn’t tell what those numbers mean even if you asked, but I can tell what 0°C outside feels, and what 100°C sauna feels. I can also tell that 21°C is a nice ambient temperature for chilling, and 15-20°C is ideal for most outdoor sports.
Yeah sure those are not necessarily nice round numbers, but I’ve used the scale all my life so it’s intuitive to me, same as the Fahrentrash is intuitive to you
No, that’s not how this works.
You understand the concept of a scale. If I asked you to rate something on a scale of 1-10, you know what i mean. It has nothing to do with intuitiveness. If I asked you to rate something on a scale of 7-23, you’d know what I mean, even though the numbers are different than what you’re used to.
So if I said it was 100F outside, you’d know that’s very uncomfortably hot, as hot as a normal person can really tolerate, because you’d recognize it as the high end of the scale.
Everyone can understand fahrenheit, some people just try really hard not to.
You really don’t understand what reference points are. The scale is useless without reference points, and I’m not accustomed to them while I have very clear ones for Celsius.
Sure I can understand that 100F feels very hot, but if I was outside in that temperature I couldn’t tell you an estimate in Fahrenheit how hot it feels
The reference points are 0 and 100! You don’t have to get accustomed to them, they are the same reference points used by the entire base-10 numerical system. It is a percentage.
And yes, you could step out into 100F degree heat and accurately estimate the temperature. Is it the hottest day of summer? Are you beginning to experience symptoms of heat fatigue? Are you saying to yourself “This is one of the hottest days I have ever experienced”, all the same stuff you’d think if you stepped outside into 37.8C weather. Then it’s probably close to the high end of the scale, i.e. 100F.
Okay so you’re making lot of weird assumptions here. I don’t know how hot weather 37°C feels, other than that for me 30+ is absolute hell. I’ve never experienced heatwave that bad for what I remember. Hottest summer days here are just about 30°C, and it’s miserable.
Reference point means that I’m able to easily understand what that temperature is.
I can easily understand 100°C though, sauna is getting too hot and I should open window and chill down with feeding the fire.
For 0-30 I can easily understand how I should dress outside, and 0°C is easy to understand because just above it and I know it’s going to be wet and slippery if there was negatives before it, and below 0 is slippery if there was positives earlier.What is intuitive to you is totally a subjective experience based on your earlier experiences and what you’re used to use to measure temperatures.
0 and 100 aren’t just “very cold” and “very hot”. They are potentially dangerously so, and you need to take extra precautions at temperatures beyond those limits. You don’t necessarily have to understand it beyond that.
It is pretty funny how your supposed completely intuitive human feeling system needs to have all these disclaimers added to it whenever you try to explain it. Perhaps it is only intuitive because you are used to it after all?
If you’d say it is 100F outside, I wouldn’t know what you mean because I have no concept of Fahrenheit. Is 100F actually hot? What is that in Celsius? Do you mean hot as in “better to wear light clothes” or “Do not set a foot outside or you will melt”?
What does it mean “as hot as a normal person can really tolerate”? What about a abnormal person?
It gives nothing of information. Just a rough indication of what it might be. Which isn’t useful at all.
Do you understand the base-10 numerical system? Do you understand percentages? Congratulations, you understand fahrenheit. You can no longer honestly say, on the internet or otherwise, that fahrenheit is meaningless to you. You are now a fahrenheit understander, whether you like it or not.
Also, your second statement answers your first question. When I say “as hot as a normal person can tolerate” i do not mean “wear light clothes”, I mean “as hot as a normal person can tolerate”. Thats why i said “as hot as a normal person can tolerate”. Happy to clear that up you for you.
Abnormalities/outliers are not something on which we should base standards of measurements.
You keep saying this but it still doesn’t make any sense. 50% heat would be average middle of the pack nice? And “as hot as normal person can tolerate” is full of shit because neither you or I have no concept of what “normal person can tolerate”, as the normal depends on your geography. And this is quite a good reason why claiming “Fahrenheit is how human feels” is just idiotic as it relies both on a specific climate and having learned that scale growing up.
I swear you Americans can get so fucking stupid on this topic, it’s like claiming that Finnish is the most intuitive language because it’s the language of how love (average love, excluding outliers obviously) feels
the numbers may be, but if you asked me to tell you what they feel like i would have to convert them to celsius first. where i live temperatures are generally between -30 and +30, and i could tell you in an instant what I would wear for a given temperature in that range. 50F though? no clue. since it’s right between 0 and 100 i guess it would be just right, temperature wise, so t-shirt and long pants?
yeah no shit, but think of it this way, if you were put into a place that was 100f, you would go “damn this bitch hot out here” and if you were put into a place that was 0f you would go “damn this joint cold as fuck fr”
Stop thinking in celsius.
What if it was 99f? Or 1f? Would your scientific “damn this bitch hot out here” change to something else?
why would i stop? there’s only one place in the world that uses another scale, and it’s dangerous for me to even travel there.
because we’re not talking about celsius? We’re talking about fahrenheit?
This is like pulling up to a car meet in a semi truck, and being really confused when nobody thinks your ride is sick.
the parent post was literally about Fahrenheit vs Celsius.
Can you remember that at temperatures near 0F and 100F, you need to take special precautions when going outside? The rest is a matter of getting used to what the numbers mean, but those are very intuitive danger points.
-18 is such an arbitrary place for “special precautions”. at 0, I know to start driving more carefully since the roads ice up. at -15, i know to wear long johns. at +15, i know to start using a thinner jacket. at -30, i know to use a thick hat and wax on my cheeks to prevent the blood vessels from rupturing. at +30, I know to use a large hat and sun cream on my cheeks to prevent them from burning.
18 is such an arbitrary place for “special precautions”
cool little trick, you see how -18 is like, pretty close to -20, yeah. You can just round them. It really doesn’t matter
see, that’s what i’m saying. having a scale that starts at “it really doesn’t matter” makes it hard to use for everyday things.
When it comes to a single number on a scale, whatever you grew up with will be more “obvious”. 100F doesn’t give me any more information than 38C does. The whole “base 10” thing only matters if you are actually doing some math to that number.
Base 10 makes it much easier to remember.
When was the last time you did math related to temperature?
base 10 is literally just 0-9 so yeah, everyone remembers that.
scaling based on the base 10 figure makes conversions easier, so there’s that.
For day to day use, it’s just a single number, no one is doing any conversions, etc, with the number. That was my point. There’s nothing to remember. Do you forget what 72F feels like? Do you have to scale it in your head?
Kelvin is used for math pretty regularly. Rankine was too.
100F definitely gives more insight as to the temperature. It’s a 100/100. That’s as hot as a person can really tolerate. If you understand percentages or how to rate things on a scale of 1-10, you understand fahrenheit.
That’s as hot as a person can really tolerate.
There’s large chunks of the world proving that false every day. For the geographically impared, the simple fact that Phoenix has existed for longer than air conditioning, proves that statement false.
And 0F as the low point is equally as useless.
That’s why I used the qualifier “really” and in another comment I mentioned “in average temperate climates” If you were more familiar with statistics you would understand how means and outliers work. Just like someone can score a movie an 11/10 or a -1/10, it is possible for the weather to exceed 100F or drop below 0F. Just not typical.
And while I didn’t say it specifically, 0F is similarly the average lowest temperature a person can tolerate/expect before beginning to experience problems.
Hypothermia can be a problem in temperatures as high as 50F. 0F is a meaningless number, outside of purely subjective “it’s cold” uses.
fun fact about phoenix, going outside on a day that’s about 100f, is not fucking pleasant they literally have air misters to help provide cooling, which barely does anything.
People are just fucking insane and will live in places like alaska where the ground is literally frozen all year round. Phoneix AZ is not “habitable”, it’s bearable. Also a lot of these places, especially in hotter dryer regions, will have covered sidewalks to provide shade, (at least historically) people would and still do wear large hats to block a lot of the sun. Even then a lot of people wouldn’t spend a whole bunch of time outside in that heat.
also, have you seen death valley? It kills people, every fucking year.
100F was defined as the human body temperature (The guy they used had a cold or something so it’s off by a degree and a half.)
That’s useful for perception of heat. When the dry bulb gets above 100F, wind only cools you down by sweat evaporation, and when the wet bulb gets above 100F, even that can’t cool you down, and you will die if you don’t get to a cooler or drier environment.
This is more intuitive than 36.5C.
What’s a dry/wet bulb?
Dry bulb is a normal temperature reading with say a thermometer. Wet bulb is that same thermometer but it is wrapped in a wet cloth to simulate evaporation of sweat.
The purpose of wet bulb temperature measurement is to fix the dangerous temperature threshold at body temperature instead of having to adjust for humidity. So if the wet bulb temperature crosses 35C/95F you know that it is dangerous to even be outside because your sweat can’t even evaporate enough to prevent you from overheating just standing in the shade.
Dry bulb is the temperature independent of humidity. Wet bulb is has a wet cloth on the thermometer bulb. This simulates how much sweat cools you in the current humidity and wind.
Measuring humidity instead and cross-referencing to get heat index is more common these days, but IMO it’s worse. 120 in the desert vs 120 heat index due to humidity is the difference between someone using a hair dryer on your face and getting cooked in a steam room, and it doesn’t consider wind and cloud cover.
Wait, doesn’t everybody walk around with a pocket psychrometric chart?
what Fahrenheit used for his endpoints was 1) the melting point of a brine mixture that he didn’t write down the ratio of, and 2) his wife’s armpit.
those “bulb” things is something i only ever hear of from americans. it’s never used here.
and I fail to see how two numbers are somehow differently intuitive. they are just numbers. also, 36.5 is too low. it’s pretty much 37.0 now, because average body temp has interestingly enough shifted since he took those measurements.
What does Europe use for apparent temperature measurement then? Just humidity and not evaporation?
temperature, wind speed and direction, and humidity are given separately. regular news report style forecasts don’t give humidity at all.
I like the saying “Fahrenheit is what you feel, Celsius is what water feels, and Kelvin is what the universe feels”.
Fahrenheit is what that one German town’s lowest air temperature measured back in 1708.
If fahrenheit was what humans felt, then 50° would be room temperature.
This isn’t the case, because humans can handle significantly larger deviations from “comfortable” on the cold side than the hot side, so again Fahrenheit gets it pretty much right.
Fahrenheit is what Americans feel, Celsius is what everyone else feels, and Kelvin is just Celsius +273.
Kelvin is just Celsius +274.15
Ftfy
Oops you’re right. I just converted 1°C to kelvin and brain farted
Fahrenheit is what everyone feels. It’s a scale of 0 to 100 of how hot it is outside. Excluding extreme outliers, it covers the range of temperatures the average human might experience. In Celsius that’s like -20 to 40. I personally use Celsius anyway, because I don’t consider it much of an inconvenience, but Fahrenheit is certainly the more human-centric scale.
This is no way describes how I feel. I almost never experience below -5C, e.g. like 20F, but from there down it doesn’t really matter if it’s 10F or -10F. You need special clothing and then you’re fine.
While my pain point is at 95F, most people I know consider “hot outside” being around 80F, and “unbearably hot outside” at around 88F. So, how is this intuitive?
this is pretty well aligned with how it works here in the US as well. The idea is literally, anything below 0 f is “fucking cold” and anything above 100f is “fucking hot”
sure, 80f is pretty damn warm, that’s how numbers work, they have a range. It’s not like there’s a distinct point where “hotness” begins and “coldness” ends
90f is generally pretty hot, but it’s mostly tolerable, you drink water, you’ll be fine, once you get into the 100f range, you start to run into accidental heat exhaustion heat stroke problems if you aren’t really on top of it.
below 0f, your nose hairs are basically guaranteed to be frozen, and any facial hair you have is probably going to get frozen over time as well.
It’s a heuristic, you’re not supposed to treat it as an ultimatum.
I almost never experience below -5C
Okay. Fahrenheit did. 0°F was supposedly based on the lowest air temperature he measured in his hometown.
This isn’t about pain points and special clothing, it’s about measuring the typical range of climate.
Exactly. He did. I don’t. So, don’t push on me some guy’s hometown lowest temperature as a 0.
(Also he did a bit more than just measure the low of his hometown, but it sorta correlates to his location)
“Bigger number is more better” also explains American sports where you get 3 points for running a bit and then play stops for an ad break and the national anthem.
Fuck it. I’m inventing a new scale.
Behold! “Disagree Degrees”. We’re going to combine the best traits of the other units. No more searching for the stupid little degree character in the character map. D for degrees or disagrees - whatever, I don’t give a shit.
0D = 0K (Like Kelvin, no negatives! That’s so dumb!) 0.4D = -40 C and -40 F 1D = Water Freezing point (Need a consistent point of scale) 10D = “Pleasant temperature” 100D = Kind of hot 500D = Really hot for people (>40C or >100F) “It’s like 500 disagrees out there!” 1000D= Water boiling (To match the freezing temp) 1,000,000,000,000D = Surface of the sun
Good luck on the math converting to other units, this temperature scale isn’t about being useful for nerd stuff, it’s all about appealing to our emotions.
For proof that this thread is just people justifying what they know as better somehow, look no further than Canada.
We do cooking temps in Fahrenheit, weather in Celsius. Human weights in pounds, but never pounds and oz. Food weights in grams, cooking weights in pounds and oz. Liquid volume in millilitres and litres, but cooking in cups, teaspoons and tablespoons. Speed & distance in kilometres, heights in feet and inches.
Try and give this any consistency and people will look at you like you’re fucked. The next town is 100km over, I’m 5ft 10in, a can of soda is 355ml, it’s 21c out and I have the oven roasting something at 400f. Tell me it’s 68f out and I will fight you.
People like what they are used to, and will bend over backwards to justify it. This becomes blatantly obvious when you use a random mix of units like we do, because you realize that all that matters is mental scale.
If Fahrenheit is “how people feel” then why are feet useful measurements of height when 90% of people are between 4ft and 6ft? They aren’t. You just know the scale in your head, so when someone says they’re 7ft tall you say “dang that’s tall”. That’s it.
Use Kelvin then, 314°K is a way bigger number
No °, just K
314 K
celsius is the yelp of temperature ratings
FOUR THOUSAND ONE HUNDRED MILLICELCIUS?!
But really it is much better for human temperatures.
It’s just intuitive, 0F is 0% hot, and 100F is 100% hot.
When the dry bulb gets above 100F, wind only cools you down by sweat evaporation, and when the wet bulb gets above 100F, even that can’t cool you down, and you will die if you don’t get to a cooler or drier environment.
How is 0F 100% cold though, most places will never get that cold, so it surely makes more sense to have 0F at freezing point of water and 100F at 38C?
Not to mention negative numbers.
Freezing point of pure water - but saltwater/brine freezes as a different temperature.
pure water at mean atmosphere pressure at sea level if we’re getting technical, but frankly human body temperature varies from 35.5C (95.9F) to 37.5C (99.5F) anyway, and that’s before considering when people are ill, so if we go down that route it falls apart quickly enough that the definition of 100 given above is clearly just as arbitrary
When I was out in SD recently the temperature was reaching 100F or above frequently and it sucked but it wasn’t that bad. Where I live in Cali and it gets that hot by the beach with humidity well into the 70% range sometimes I literally felt like I was about to die just sitting inside with a fan blowing right at me. Humidity is such a huge factor.
Being 41% of the way to boiling water sounds pretty hot to me, too.
“Intuitive” is a meaningless metric for a single scaled number. Whichever system you are used to will be the more “intuitive”.
Also, climate can play into which system feels more useful. Where I live, 100F occurs only rarely (and since air conditioning is almost ubiquitous, not something I’d bother looking out for), while 0C is an outdoor temperature that I do need to be aware of for half the year.
I disagree that either would be just as intuitive. Fahrenheit being 0=cold and 100=hot is intuitive because there are a lot of things we do in the world that exist on a scale of 0 - 100. Percentages, just off the bat. Also, fahrenheit has a higher degree of fidelity in the temperature range that we use.
Celsius’s general temperature scale is like -10 - 40 which is absolutely not intuitive because it doesn’t look like any other scale we use as humans. I agree that we get used to Celsius fast and it’s a fine it’s not like it’s super confusing (and Celsius is so much more useful scientifically).
Which system did you grow up with? Because I grew up from the start with Celsius und it is 100% intuitive to me. Everytime you americans use your funny temperature numbers I have to stop and use a tool for transforming it or I simply ignore it and go “low means cold and high means hot, how high? Ain’t nobody got time for dat!”
So I disagree with your notion that Fahrenheit is intuitive. The system you grew up with and have multiple experiences as reference points for, is the system you feel is intuitive is also my opinion.
That’s not either scale being intuitive or unintuitive, that’s your familiarity with one over the other.
I got curious so I did some research on the definitions and why everything is this way. It looks like they originally picked the coldest thing they had (brine, possibly inspired by the coldest weather), the freezing point of water, human body temperature, and the boiling point of water. It was supposed to be brine at 0, water freezing at 30, the human body at 90, and water boiling at 240. Fahrenheit then recalibrated his scale slightly to make his math (and thermometer design and production) easier, and also because he noticed water actually boiled at 212 by his newly modified scale.
Looking at it like that work the context of what they had at the time and what they were trying to do, it makes a lot of sense.
What you grew up with =/= what is intuitive.
That is not what intuitive means. You’re talking about what’s “familiar”.
Familiarity is subjective. Intuitiveness is objective.
If we want to go that road, intuition is according to Wikipedia:
Intuition is the ability to acquire knowledge, without recourse to conscious reasoning or needing an explanation.[2][3] Different fields use the word “intuition” in very different ways, including but not limited to: direct access to unconscious knowledge; unconscious cognition; gut feelings; inner sensing; inner insight to unconscious pattern-recognition; and the ability to understand something instinctively, without any need for conscious reasoning.[4][5] Intuitive knowledge tends to be approximate.[6]
Since every temperature system needs an explanation, namely the reference points, no system is or even can be intuitive per this definition.
Never said either one can’t be intuitive, just that the scale of farenheit has a precedence outside of it being an arbitrary temperature measurement by being a scale that goes from about 0 - 100.
If you had never used either scale and some one asked: “which is more intuitive, a temperature scale where -10 is really cold and 40 is really hot or one where 0 is really cold and 100 is really hot?” I know which one I would pick because I’ve done things before like calculate percentages and work in a base 10 system so it makes sense for the scale to be between two orders of magnitude.
But that is what we others are saying: there is no “more intuitive” system, just one you know better and can quicker evaluate how it would feel! So you agree with us.
Everything you said can be said about Celsius scale as well.
There is also a precedence for Celsius more than just an arbitrary number between 0 & 100.
A scale for liquid water, you know, the stuff that is the reason why we call our little spaceship "the blue marble"and why we even have this discussion, because it is the basis of all life on earth, is also not a bad choice for a number between 0-100.
And you made me curious: in what context did you have to calculate percentages of temperature that were not in Kelvin? Because as soon as percentages and temperatures are close to each other in one sentence the only example I can think of are things like reaction kinetic calculations and those are neither in Celsius nor in Fahrenheit.
You should examine your definition of intuitive. Yes, technically nothing is intuitive it’s just based on what you know because intuition is also based on what you’re used to.
By your logic, if you compare a machine that powers on by pressing a big glowing red button labeled “ON” and one that turns on by you performing the haka in front of a camera while reciting a Shakespeare sonnet backwards you might say that there is no “more intuitive” way to turn on a machine, just one you know better and can perform quicker!
You aren’t reading what you’re replying to because I said in a previous post that it’s easy to get used to Celsius and fahrenheit and there’s no difference to either and I also already said that Celsius is better for science because it’s based on water.
Everything you said can be said about Celsius scale as well.
At this point you’re just lying or further proving that you didn’t even read the post you tried to respond patronizingly to. I said that the Fahrenheit scale is intuitive because it’s a 0-100 scale which is similar to other scales we use all the time and works well for our base 10 counting system being a scale essentially between two powers of 10. Neither of that can be said for Celsius and that’s so obvious I think you just didn’t read it before replying.
And hell, on top of all this, I think we should all switch to using Celsius! Because as I mentioned it’s easy to grasp both scales and using Celsius makes understanding a lot of science easier which I think is the only real argument in this arbitrary choice between the two! But I’m out here explaining the use of Fahrenheit because people here can’t grasp my explanation for why people might use it and are acting like they’ve got the defeater to a post they didn’t even read!
But fahrenheit is not a 0-100 scale. You have just arbitrarily picked out 0-100 because that makes your brain more easily understand the non-intuitive system which is fahrenheit.
It has only been 100°F once in the last century. Nobody has any point of reference to make this intuitive. 30°C/85°F is defined as hot around here. 40°C/100°F is defined as national emergency.
“It has only been 100F once in the last century”
Lmao what?? Go ahead and find me a source for that.
I guarantee you it reaches 100F regularly during summer in many temperate climates, that’s not even including warmer regions.
Do you think your little small town is the only place in the universe?
it reaches 100F regularly during summer in many temperate climates,
Not when it’s near the sea, like most of western Europe. It’s the same shit as “why don’t you have airco?” Because it was never that hot.
Tell that to the gulf coast, or Mexico, or central America, or Africa, or Australia.
Your experiences are not universal. Just because you’ve never seen 100F doesn’t mean no one else has. That’s absurd.
The heat index gets over 100°F in much of the southern US every summer
“cold” and “hot” are completely non-descriptive and useless parameters for your supposed “intuitive” system.
Lol, 0F is not 100% cold. That is barely cold unless you live in very warm place
Do you live in northern canada?
Europe
People do live outside of North America. I know that must be news to you, but it is the truth.
0F is 100% cold, and 100F is 100% hot.
So 50% is perfect temperature, no?
I love it when it’s -10% hot in winter nights or 110% hot around the equator. Makes perfect sense.
Yes, it does, actually, if you understand how thermal energy works.
Yes, it does a better job of impressing that is all of the hot (or cold), and then 10% more than the difference between 38 and 43
i assure you, we who grew up with celsius absolutely know the dire difference between 38 and 43. 38 is death, 43 is the crimson realms where even souls wither.
all this “which one is better for x” is nonsense, you develop a feel for whichever you grew up with. it’s just that the math is less stupid with metric. that’s all.
Any of the systems is better if you have an intuitive understanding of it. I don’t know what 107 F would feel like, just as you don’t know what 42°C feels like. But it’s not a thing where one is inherently better than the other…
YOU’RE BOILING?!?
Oh, you’re just an inbecile who likes to prove the movie Idiocracy is actually a documentary.
IT’S OVER THREE HUNDRED KELVIIIIIIIIIIN!
That’s why I only use Kelvin. 314.15 sounds like 3 times more “WTF HOW HOT IS TODAY??!?” than your paltry 107
