    No need to convert. 0 to 40 is the part of the scale for weather, where 0 is dangerously cold and 40 is dangerously hot.

      No need to convert? What do you mean? Are you saying if I just intrinsically knew Celsius for weather I wouldn’t have to convert Celsius? Because that’s obviously true, but I’m just explaining I don’t intrinsically know Celsius in that way.

      Also, even if I did get to know Celsius really well, I would still have to convert it every time someone uses Fahrenheit, which is pretty much all the time in the US.

      Lastly, what do you mean, saying 0 C is “dangerously cold” and suggesting that below that temp is outside of the bounds of what is used for weather? Where I live the temperature stays below 0 C for long periods of time, never going above it.

        If you know those two numbers, 0 and 40, you can get a general idea of what the temperature is in Celsius without doing any math. If you hear 20, you know that’s a moderate temperature because it’s right in between. If you hear 30, you know that’s fairly warm. If you hear 10, you know that’s chilly but not freezing. Below 0 or above 40 are extreme cold and extreme heat, respectively.

      What’s 28° C? How can I envision in my mind what that means?

      0-40 as a scale. 28 is about 3/4 between the two. So it’s towards the hotter side but how far into it?

      It’s 82.4° F

      Low 80s. I know exactly how low 80’s feel.

      0-100 is easy to compare with %

      82.4° F is 82% hot.

      Humans like it around 75% hot between 50-100.

      So 82° is hot but not pushing 90s

      You can get a general idea of temperature very easy.

        35°C with 100% humidity can be fatal to humans

        46°C with 50% humidity can be fatal to humans

        Humans can not survive for extended lengths at these temperatures and humidities.

        Saying “40 ain’t dangerously hot” is dumb.
