That is technically correct, regardless the scale you opt for.

I’m not sure I agree with the take for farenheit. It’s an arbitraty choice, and to me who grew up in a country that uses celsius, I find that far easier to understand and farenheit may as well be random numbers to me.
Zink@programming.dev 11 months ago
Whatever your grew up with will always seem more intuitive for most people. But given that I grew up with Fahrenheit, the whole “0 is cold as fuck, 100 is hot as fuck” thing works for me.
PancakeLegend@mander.xyz 11 months ago
Farenheit is asking Americans how hot they feel.
Sigh_Bafanada@lemmy.world 11 months ago
Yeah after I discovered that sort of meaning for fahrenheit, it made a lot more sense to me. So no issues with fahrenheit, but imperial is still crazy to me
Zorque@kbin.social 11 months ago
"I grew up with a completely different scale, so this scale makes no sense to me!"
Well no fucking shit.
Khrux@ttrpg.network 11 months ago
I was trying to be polite as to not trigger Americans which generally happens when you critique Imperial measurements. The post makes no sense to me as it assumes that Farenheit is correct for humans to communicate temperature. The post should read.
Celcius is basically asking water and most humans how hot they feel, Kelvin is basically asking atoms how hot they feel and Farenheit is basically asking me how hot it feels because I didn’t learn the others.
AI_toothbrush@lemmy.zip 11 months ago
I know someone who knows both “natively” and celsius is much more logical to them because 1. kelvin has the same steps as celsius so for any science its much easier 2. freezing is 0 celsius so for weather(the thing you use temperature most commonly for) its really useful. Same with cooking.
C126@sh.itjust.works 11 months ago
So humans feel cold at 0F and hot at 100F? I dont think thats true. Humans start quickly dying at something around 32F and 180F. Fahrenheit is complete nonsense. It has nothing to do with humans. And considering humans are mostly water Celsius seems a much better fit.
Theharpyeagle@lemmy.world 11 months ago
They do? 32F is 0C, it very routinely gets below freezing in many inhabited parts of the world, including the US, and people get along just fine with some precautions. Likewise with 100F (not sure what 180F has to do with it). So yeah, 0F and 100F are around the extremes of what humans regularly experience.
doggle@lemmy.dbzer0.com 11 months ago
In aggregate this is absolutely true, though not the point anyone is making.
Humans will die of dehydration or heat stroke quite quickly at temperatures well below 180F. In fact that’s far hotter than the hottest recorded temp on Earth (~135F/56.7C) (not including human-made environs like a sauna or outliers like an active volcano) so I’m frankly not sure what point your even trying to make here.
The latter statement is manifestly false. Fahrenheit was originally supposed to have 90 degrees as the average humans body temp (no clue why 90 and not 100). Due to inaccuracies in measurements of the time, It was later changed to 96 and then 98.7. Still no clue why not just 100, but the fact remains it was based on human body temps. The zero point was selected using the freezing point of a brine mixture. No real defending that one, it was pretty much arbitrary.
doingthestuff@lemmy.world 11 months ago
Where I live the weather varies between -5 to 95. That’s pretty close to a 0-100 scale which is universally understood. It’s almost like metric for the human experience.
JayObey711@lemmy.world 11 months ago
Where the fuck did you grow up? On Venus?
MargotRobbie@lemm.ee 11 months ago
Fahrenheit was not an entirely arbitrary choice: it was defined based on two points of reference that could be measured at the time: the freezing temperature of an ammonium chloride brine is used as 0, and the best estimate for the average human body temperature is set at 96.
Over time, as the freezing point and boiling point of water at sea level atmospheric pressure proves to be more accurate reference points, the Fahrenheit scale was adjusted to provide exact conversion to Celsius.
booty@hexbear.net 11 months ago
it’s not arbitrary, it’s based on the uh, the freezing temperature of uh, ammonium chloride! we’re all familiar with how cold that is! and, and, and, uh, the upper end is, uh … they decided on 96. it’s not arbitrary!!! wojak-nooo
iturnedintoanewt@lemm.ee 11 months ago
…96? How is 96 a point of reference when you are making a scale from scratch?
rainynight65@feddit.de 11 months ago
Are you telling me they were able to measure those things, but not the boiling and freezing point of water?
Sure, let me just whip up that ammonium chloride mixture and travel somewhere where I can get it close to freezing so I can know the zero reference of that scale. What, did the just carry that NH₄Cl around for convenience?
Fahrenheit was proposed in 1724, Celsius dates back to 1742, so there wasn’t that much time between the two.
TheTetrapod@lemmy.world 11 months ago
I don’t know if this’ll help, but I find it interesting. Fahrenheit was designed to make creating thermometers easier. You pop your new thermometer into some ice water, call that 32, pop it in your mouth, call that 96 (human body temperature is actually 98.6, but these weren’t the most precise instruments), and then you can just keep dividing the space between them in half until you get 64 degrees.
Obviously Celsius is more scientific and practical in modern times, but I think Fahrenheit is fascinating, if nothing else.
eee@lemm.ee 11 months ago
I don’t understand your logic. I could just as easily change your text to say
anguo@lemmy.ca 11 months ago
That’s some weird logic there. Why 32 and 96? From what I remember, 100 was supposed to be human body temperature (but he had it wrong), and 0 was the coldest temperature he could achieve with brine.
Frozengyro@lemmy.world 11 months ago
I group up with F, I find it far easier to understand. Celsius is slightly less random, but someone still arbitrarily decided it should be 0 to 100 for the liquid state of pure H2O at sea level. It could have been based on any other number of ranges.
Venat0r@lemmy.world 11 months ago
I’m biased living in a °C country, but water seems like a better choice than anything else, since water is a common element that we can easily observe its phase changes and those phase changes, and have to interact with on a daily basis.
Although if I was to improve it I think I’d base it on the temperature range that salmonella can grow, as that seems like it might be useful to be able to remember more easily 😂 🧑🍳
imasnyper@lemmy.ca 11 months ago
I grew up in Canada, but in a temperate climate area on the border with the US. Winter? Use Celsius. Summer? Use Fahrenheit. For me Celsius makes a lot more sense right around 0C. After about 15C my brain switches over and starts using Fahrenheit. I like the Fahrenheit scale from 60-100F for gauging the summer months. The Celsius scale isn’t granular enough. It feels like there’s a big difference between 18C and 22C versus the comparable 64F-72F. But I also was taught early a quick and dirty conversion. C to F, double and add 30. F to C subtract 30 and divide by 2.
Pok@lemmy.world 11 months ago
I don’t think I can tell the difference if something is only one degree apart in Celcius, let alone Fahrenheit.
Comparing an 18C day to a 19C day, for example, I challenge anyone to notice a difference. A 64F to 65F day? Good luck.
I agree with the Celsius scale making sense around zero. Water freezing is probably one of the most relatable, quantifiable examples of a temperature point for the most humans. However, lots of people don’t live somewhere that it snows, or even own a freezer.
So what’s the most common touch point for people? I’d go with water boiling. I can’t really think of what sort of person who did not have exposure to that at some point. That should be the zero point, the common denominator.
A2PKXG@feddit.de 11 months ago
Celsius temperature are often given in steps of 0.5. for temperature records in summer the news report it down to an accuracy of 0.1

I love Fahrenheit, it’s awesome. It’s the only non-metric unit I prefer.
cawifre@beehaw.org 11 months ago
It makes sense that you find the system you grew up with to be more intuitive, but I grew up with fahrenheit, and I think you’ve misunderstood the assertion a little bit.
The older observation that this meme is riffing off of is that 100°C is the point at which water stops being sloshy and starts being steamy, whereas 100°F is the (much fuzzier) point at which humans stop moving around and start decomposing.
The Kelvin addition muddies things because 100K isn’t really significant.
Kusimulkku@lemm.ee 11 months ago
But there’s numbers below 0 and beyond 100. I don’t know why some are so focused on just those two points
jcg@lemmy.world 11 months ago
Of course it’s all pretty much arbitrary. But I think the point was more “celius puts the scale of heat levels of water heat from 0 - 100, farenheit puts the human feelings scale of heat from 0 - 100”
Pok@lemmy.world 11 months ago
One of those things is more specific than the other.
MrSqueezles@lemm.ee 11 months ago
Fahrenheit measured human body temperature (which he thought was a constant) and called that 96 degrees. We now know normal body temperature is about 98.6 degrees F, but back then, his instruments weren’t as accurate. The number 96 was chosen for its divisibility. It has many divisors (1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96), making it easier to mark subdivisions on the thermometer.
It’s a scale partly defined by human body temperature, which is, I think, the point.
GoodEye8@lemm.ee 11 months ago
There are many stories on how Fahrenheit came up with the scale, the body temperature one is just one of many. It’s no more true than the one where he took the Romero scale as baseline and multiplied it by 4 to get rid of the factorial.
Pok@lemmy.world 11 months ago
Wait, he chose 96, or he measured it?
happyhippo@feddit.it 11 months ago
Same.
Not to mention that the 0-100 range thingy really depends on local conditions. I mean, depending on where you live, there are parts of the scale you’ll never use.
I’ve never in my entire life lived in a place where the lowest temp got anything close to 0°F.
My range of values is more -5°C - 45°C, or 23F - 113F.
23F for me is already fucking cold, and 100F is nowhere near fucking hot anymore (thank the entire humanity for climate change).
So whichever scale, for me they’re still just a bunch of numbers. But at least Celsius is used in “science, bitch!”
AOCapitulator@hexbear.net 11 months ago
Climate change is not all of humanity’s fault
It’s a very specific very very very tiny group of humans who are doing this to us
Donkter@lemmy.world 11 months ago
Of course whatever you grew up with will be far easier to understand. I grew up in a country that uses fahrenheit and I find that far easier to understand and Celsius may as well be random numbers to me. But if you look at the range of temperatures experienced on earth and the systems people have used to measure other things (including the metric system.) It’s clear to see that fahrenheit has more fidelity and maps more cleanly onto that range.
Phrodo_00@lemmy.world 11 months ago
Never understood the fidelity argument. It’s not like decimals suddenly stopped existing because we’re dealing with temperature.
As far as measuring weather, they’re more or less the same. Fahrenheit is handier on the high end but useless in the low (0F doesn’t mean anything). Celcius is a lot more useful at 0, and then the higher temperatures are around 30-35 which is fine, but as cool.
Where celcius shines is when you start combining it with other units like calories and then Joule and Newton, etc.
WarlordSdocy@lemmy.world 11 months ago
At least personally I think the 0 to 100 scale with the average global temperature being somewhere in the mid 50s I think makes sense. Sure there’s some people in warmer places and some on colder places that will say 0 and 100 farenheit aren’t that bad but for people in a more temperate environment it works as a good scale. But yeah I do agree at the end of the day it is whatever you grew up with and it doesn’t really matter that much. It’s just that for temperature there isn’t as concrete of a reason to switch to metric compared to lengths and weights.
MonkderZweite@feddit.ch 11 months ago
But you are still using imperial.
Damaskox@kbin.social 11 months ago
Which countries/cultures even use Farenheit?
joenforcer@midwest.social 11 months ago
The United States. We basically pretend that Celsius doesn’t exist in all applications of temperature. Weather, cooking… it’s all in Fahrenheit.
reminiscensdeus@lemm.ee 11 months ago
A useful way to think about it (and I think what the OOP is saying) is to think about it as a scale from 0-100. Where 0 is like the coldest humans can deal with and 100 is the hottest humans can deal with. Obviously this isn’t strictly true (it gets to like 115 in like death valley) but as an imperfect generalization it’s pretty useful.
ILikeBoobies@lemmy.ca 11 months ago
Then 50 is the optimal temperature right?
ProfessorOwl_PhD@hexbear.net 11 months ago
Yeah, no, that’s not helpful at all - what I consider cold and what my mum considers cold are very different temperatures, and what I consider hot and my neighbour considers hot has an even bigger difference.
You rationalise it with the “human scale” idea, but really you just know the range of temperatures you’re personally comfortable in, just like everyone using Celsius does.
tdawg@lemmy.world 11 months ago
Ssshhh. Just give it to us. We Americans don’t have much else left
doggle@lemmy.dbzer0.com 11 months ago
100 F is roughly a human’s body temp. (Actually 98.7 avg, but close anyway)
0 F is goddam cold. (This one’s pretty arbitrary ngl)
That probably isn’t very helpful.
Fwiw, Celsius isn’t much better if you didn’t grow up with it. 0 C is pretty cold, 100 C can give you severe scalds. The actual range the people will encounter in weather in their day-to-day lives is all over the place regardless.
Perhaps we are destined to stay divided
Khrux@ttrpg.network 11 months ago
I’m UK based and ~0°c to ~30°c (32-86f) covers 90% of the year for celcius. It’s still pretty unhelpful but I don’t think that feels any harder than using Farenheit in day to day use, I agree that it’s largely all arbitrary, but that’s as good of a reason to just use that one that’s scientifically useful too.
Pok@lemmy.world 11 months ago
Why does it have to be based on weather? There’s plenty of other reasons to measure temperature. Some with handy reference points that lots of people are familiar with.
ILikeBoobies@lemmy.ca 11 months ago
Yeah it’s less human based than Celsius since humans exist equally on the sides of 0 (-40 to 40)
Thief_of_Crows@sh.itjust.works 11 months ago
Fahrenheit is roughly a 0-100 scale of “places humans can conceivably live”. 0-100 scales are more intuitive than a scale from like -15 to 40, which is approximately what celsius uses for the temperatures humans can live at.
Pok@lemmy.world 11 months ago
If only there was something more specific that a wider range of people could relate to.
schnapsman@lemmy.world 11 months ago
Fahrenheit has too much precision. Humidity makes the difference between a degree F virtually meaningless. 0-100 is nice but then the minus degrees don’t mean anything. In F you go from already fucking cold to even colder. You can think of C being 0-30 with minus being a threshold of more serious cold, poor road conds etc. Celsius is more elegant than it might first appear. Also using it is less confusing and cringey for non-USians.
sooper_dooper_roofer@hexbear.net 11 months ago
Personally I like Fahr better because there’s more resolution
I’m also really good at guessing the current weather, often to within 1 degree F and 3% humidity
teichflamme@lemm.ee 11 months ago
I have never encountered a single situation where having more resolution would have done anything for me.
