    Fahrenheit scale is super arbitrary and it’s hilarious when it is posed as a “human-centric” scale.

    The Fahrenheit scale is literally based on what was thought to be the limits of human comfort though. 0° F started as the lowest measured temperature in Daniel Gabriel Fahrenheit’s hometown, and 100° F was his estimate of normal human body temperature.

    You think it’s arbitrary because you’re used to a different scale. To me, having a scale go from 0C to 40C seems arbitrary, especially because I live in an area where for 3 months out of the year, it’s constantly below 0C, and it’s critical to know the difference between -5C and -15C, rather than just lumping them both into the same “sub-zero” category. I’m the same vein, categorizing 10C as “jacket weather” is borderline useless. The “jacket” I’m going to wear at 10C is much heavier than the one I’m going to wear at 17C (if I wear one at all), for example.

    By the way, you can do the exact same breakdown of the Fahrenheit scale, except it’s more than twice as granular, and it goes from 0 to 100, like a bunch of other metric measurements… It boggles my mind when metric users use the 0 to 40 Celsius scale up as an argument against Fahrenheit.

      Fahrenheit’s hometown is certainly the metric everyone should use /s

      Celsius is not arbitrary, it is based on objective physical reality, and the only arbitrary thing about it is atmospheric pressure, which is more or less equal on the sea level. The rest is us finding convenient patterns, not the other way around. 0-40 is not a scale, it’s an arbitrary range and adaptation of Celsius to subjective feelings of hot and cold - one that you ironically need for Fahrenheit, too. Actual thermometers normally go -50°C to +50°C.

      On sub-zero, it is the same idea: -5°C is a weather for a light winter jacket, -15°C is a weather for a heavy winter jacket, -25°C is for heavy jacket and some pullover, etc etc.

      The 0-40 argument demonstrates that we don’t need some arbitrary scale based on Fahrenheit’s recording in his hometown in order to conveniently estimate temperature. The groups for each dozen of degrees are just for easy reference. 17 degrees is optional for your taste, to me it’s light jacket weather in overcast or t-shirt weather when sunny. There are no perfect temperatures for anything and anyone, and it just doesn’t make sense to get into more detail.

      As per granularity, people invented decimals, but normally it’s simply not necessary to tell the difference between 17°C and 18°C, let alone between 63°F and 64°F. There are so many factors influencing the temperature feeling, and one degree ain’t one.
