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
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.
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.
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.
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?
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
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 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.
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.
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 here
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?
