You're correct. In a lab setting, 0C and 100C are not arbitrary.

In the weather forecast, they are.

Which ties into your final point, it's hard to define a scale that is best for everything, which is exactly what I've been saying this whole time. Fahrenheit is better for some things, Celsius for others.

The only reason people in this thread are saying otherwise is because for some reason they've tied up some significant part of their self-worth into their belief that "lmao DAE fahrenheit bad amirite??1?", and they mistakenly believe that those of us that understand nuance are trying to belittle or disparage them in some way. I assure you, we are not.

What makes you think humans, an endothermic species, desires exactly 50% thermal energy? We enjoy the 70F region because we are warm blooded mammals.

"In International Sauna Championships the sauna was heated to 110°C" Yeah. And 2 people collapsed, 1 died from it. https://www.bbc.com/news/magazine-10912578 A 5-time champion who had excellent tolerance.

"Exactly. Because that is required to understand what the numbers mean (in celsius)"
Exactly, because fahrenheit doesn't require such a random set of arbitrary associations. Congratulations for understanding what I said while trying so hard to miss the point.

Look, you can argue all you want. The fact is that both systems have their applications. I don't believe you genuinely disagree with this statement. I think you're just here because you want to sling shit at people that are different than you. Nothing you say will make Celsius better at determining ambient temperature, nothing you say will make fahrenheit better for use in a lab. Get over it.

"Can be" Yeah if you're submerged in 50F water you will succumb to hypothermia due to the specific heat of water.

But we're not discussing swimming pool temperatures, we're discussing air temperatures. You are not actively in danger of imminent hypothermia at 50F air temp like you are at 0F air temp.

But of course you know that already. You're not here arguing in good faith, you just want to sling shit at people that have a better understanding of the world than you. If you want to use Celsius for everything, go ahead. No one cares. But the intelligent world will keep using both.

Lmao and there it is.

"You americans"

It was never about temperature. You just love any excuse to shit on people that are different.

God forbid a country teach the value of both systems. Your tiny mind evidently cannot comprehend the very idea of 2+ methods of measurement.

And yes, no matter how much you screech to the contrary, there is a maximum safe temperature a human can exist in, and it's roughly 100F. Yes that varies based on an individuals tolerances, which is why I've specified on many occasions that it's representative of the average climate in a temperate region. If you were capable of reading, you'd know that.

Lmao your sauna is not clearing 100C, that's well past the point at which saunas can become hazardous to your health. If you genuinely run your sauna that hot then start looking into competitions because you're gonna blow all those professionals out of the water.

Also I'm not making any assumptions here. That's just you trying to grasp at straws to save your failing argument. You don't know what 37C feels like? Weird, I know what 100F feels like. I guess fahrenheit is just more intuitive than Celsius (by your logic, anyway).

Also, all you've done is list a bunch of understandings about Celsius that depend entirely on experience and prior knowledge. "Above 0 is like this, below is like that, I know how to dress for 0-30" This is all stuff you had to be taught/learn, the exact opposite of intuitive.

But I can say to someone unfamiliar with either system "Fahrenheit is a 0-100 scale of hot how it is outside" and they know almost everything they need to know about fahrenheit.

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.

"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?

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.

I 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.

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.

Okay so fahrenheit has a well-defined high and low, but an arbitrary freezing point of one certain chemical. All other chemical freezing points are arbitrary.

Celsius has an arbitrary high and low, but a well-defined freezing point of that same chemical. All other freezing points are arbitrary.

If your motivation is to minimize the amount of arbitrary values you have to memorize, fahrenheit is the clear winner.

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.

But to understand "x out of a possible y" you have to understand scales, or at least percentages which is the same concept. Then, if you understand percentages, you understand fahrenheit.

Honestly more places should do what the U.S. does and just teach both (and Kelvin). Because ultimately there isn't one perfect system of measurement for every possible application. Celsius is of course better in lab settings, Fahrenheit is better for cooking and meteorology.

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.

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.

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.

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.

Also it's a 0-100 scale of how hot it is outside, and it requires no prior understanding to use it as such.
