I went down a huge rabbit hole cause of this. I personally like °F over °C but agree it’s arbitrary. So I tried to make a scale that started at the coldest air temp on earth (some day in Antarctica) and went to the hottest day on earth (some day in death valley) and put the coldest day at 0°A and the hottest at 100°A.
Sadly this made a scale that was less precise than I’d like. I like that I can feel the difference between 73°F and 74°F and don’t want to have to use decimals.
So maybe the end points could be only places where people actually live. Well it looks like some people live in Russia around -70°C and some people live in northern Africa around 50°C so if you just take °C and add 60 you can get a -10 to 110 scale where most temps would fall between 0 and 100. Still has the unit difference of °C (which I don’t like) but I like that most temps are between 0 and 100. I also don’t really like negative temperature since it seems wonky.
To “fix” the unit scale you could just multiply everything by 2 so the difference between each full degree is half as much. So temps would be between -20 and 220. °A = 2(°C + 60) °A = 2(°C) + 120
And it turns out I (basically) created the Fahrenheit scale but moved. °F= 1.8(°C) + 32
TL;DR: I’m stupid and this was fun but also a waste of time lol
Celsius is tied to points of ice melting and water vaporising. Since water is very important for the life on our planet, it makes even more sense than arbitrary chosen meters or seconds.
And similarly, Fahrenheit seems to be tied to the internal temperature of the human body, with 100 degrees being the maximum that the average person can handle before their organs start to be damaged.
But not everybody experiences temperature the same, so using a system based on what ‘humans’ like, seems a bit useless
Once you’re below -6C or so you just need more insulation. -6C to 10C in many ways can be harder to manage due to humidity, especially in wet conditions. My prolonged exposure experience is only down to -30C. I did not have enough insulation, but an extra base layer, better gloves/boots would have been sufficient. I was fine with fairly light clothing down to -18C. I hear -50C is where it starts to get really harsh again.
Your body also adjusts a lot. In the Summer in wearing a puffy indoors at 10C(50F) but in the winter I’ll go out in a t-shirt at -10C, especially if doing manual labor.
That’s crazy. My body doesn’t adjust to cold weather. I’m always cold when it’s cold outside, and I’m talking about cold which is considerably warmer than the cold you’re talking about.
