    It’s taught but not really for weather. So while I know the boiling and freezing points of various substances in Celsius, I don’t have instant recognition when I hear a Celsius temperature, I have to convert it in my head.

      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.

          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.

        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.
