You’re totally correct that Celsius is the more sensible scale with easier to replicate reference points (when using water). It was also invented almost 30 years after the Fahrenheit scale and with all the insights gained from that period of technological advancement. In fact in the modern day the Celsius degree size is defined in reference to the Boltzmann constant since Celsius is essentially the Kelvin scale with the numbers moved around.

It also used 100 as the freezing point of water and 0 as the boiling point when originally proposed, which changed after Anders Celsius died because everyone knew that was a weird way to do it.

As I understand it, yes it was a saturated solution.

I’m saying that 0F is waaaaaaay more dangerous than 100F so the logic of those particular temperatures being the 0-100 ends of the scale can’t be explained by how dangerous they each are.

idk about that though, i mean maybe if you go outside completely naked, sure. But idk who would be doing that. I’ve regularly been outside in close to 0f temperature in lighter clothing, it’s not pleasant, but im not going to freeze to death within twenty minutes. Plus you can also do physical activity, and as long as you regulate sweat, you’ll be fine. Although sweat can be particularly dangerous in colder weather.

Almost everyone would be fine staying outside for 30 minutes at 100F without no external help (shade, cool drinks etc). Almost nobody would be fine after staying outside at 0F without external help (parka, thermals etc).

i think that’s unreasonable though, you just wouldn’t be going outside at all in those clothes, in the same way that you wouldn’t go outside in 100f weather in a full winter get up. You would literally die.

140f as a relative measure is wild to me, in 140f if you’re outside without an air conditioned vehicle (death valley) and you don’t have water you will die within about a day. 100-130f is considered “extreme heat” in death valley, which has a website that you can pull up for some relevant information. Once your body is over about 110f internal temperature, you’re fucking dead. Unless you have a way to either redirect sunlight from hitting you, and water to replenish that lost from sweat, you die really quickly.

0f isn’t considered “extreme cold” that would be something like -40c (or f, they’re the same) where basically everything starts to freeze, and i’ve seen people do overnight camping in that weather. It’s perfectly doable, obviously not without gear, but who isn’t bringing gear? Hell you can bring a space blanket with you, with the right gear you can easily exist in 0f weather for a prolonged period.

I’m not sure where you’re quoting the “really dangerous” from because i just said both of them are “really hot/cold”

But I don’t explain the insane system with “it’s because the two ends are reallllly dangerous.”

did i say this anywhere??? I feel like i’m schizophrenic.

So why not make the temperature go to the hottest? Let me guess, 0 isn’t the coldest either in America, right? It’s just so arbitrary, and pure cope to say it’s the best way to describe temperature.

I mean, I have clothes. Long underwear? Layers? Coats, gloves, hats, scarves?

They say you can always put on more clothes if you’re cold, but that’s not really true. Insulation adds bulk, and bulk reduces mobility. Around 0F is where I start to have real trouble wearing enough clothing to stay warm while still being able to perform the activity that has me outside in that weather. Somewhere around 0F, clothing doesn’t really cut it, and I need shelter or additional heat.
