      I don’t think how hot humans feel works at all, it’s just arbitrary

      Can humans survive 100 degree heat? Yes so it doesn’t represent 100%

      150 for 3rd degree burns (almost instant), does Fahrenheit go off base 150? Also no

      What about cold? Well -40 requires a lot of layers, so then +40 should be pretty hot for humans right? Nope, because it’s not related to humans at all

        I don’t think how hot humans feel works at all, it’s just arbitrary

        Fahrenheit was originally calculated to be 64 even divisions between water freezing temp and human body temp, then 32 more units below freezing.

        Then ambient human body temp was recalculated from 96F to 98.6F.

        So it’s not exactly arbitrary. It’s based on powers of 2, based upon an inaccurate measurement.

          I mean, the temperature 0 was assigned because it was the lowest temperature that winter in Fahrenheit’s town, and the “powers of two” was only chosen because it was simple to mark degree lines on his instrument. Feels quite arbitrary to me…

        Why do these matter? What percentage of humans live where it’s regularly -40 degrees? Why does the scale need to be perfect in your opinion? And how is Celsius better?

          I have no idea what this means.

          Humans can survive 100 F so it’s not a scale of 0-100, which you would expect for a system based on humans

          Why does the scale need to be perfect in your opinion?

          The person I responded to said it was based off humans, I was arguing that it wasn’t because no patterns exist in relation to humans

          And how is Celsius better?

          Well the person claimed it’s based on the temperature of water at sea level with 0 being freezing and 100 being boiling. This would be the 0-100% for water

            Technically, water can still go higher than 100°C, same as humans can go higher than 100°F. Water turns into steam. If the temperature continues to rise, the steam would theoretically enter a plasma state. Then, you could say the water has “died” as the atoms and molecules lose their electrons.

            Humans can survive 100 F so it’s not a scale of 0-100, which you would expect for a system based on humans

            No one said it’s a scale limited from 0 to 100 on the basis of survivability. That’s something you just made up on the spot to push some weird narrative.

            The person I responded to said it was based off humans, I was arguing that it wasn’t because no patterns exist in relation to humans

            I again have no idea what you’re saying. The patterns of 0 being low and 100 being high isn’t a pattern related to humans? That’s obviously not true. We use 0 as the bottom and 100 for the top on a lot of other things.

            Well the person claimed it’s based on the temperature of water at sea level with 0 being freezing and 100 being boiling. This would be the 0-100% for water

            Why are you limiting 0 and 100 as cut offs?

        No one said it represents “100%”, whatever that is even supposed to mean. 100F is really hot outside. 0 F is really cold. Doesn’t have to make 100% sense. Celsius doesn’t make perfect sense either. There is no perfect magical scale that works completely.

          Fahrenheit only works like that if ur used to extreme cold tempature. Anything under 10c (50f) is cold af to me and 38c (100f) is hot sure but nowhere near as cold as -17c (0f) is

          “really hot” and “really cold” are supremely useless terms in this context though.

      Yeah, this gets repeated (by Americans) every time a discussion about temperature measuring systems comes up, but it is complete nonsense. The vast majority of Earth’s population are completely fine with measuring how hot they feel in celsius, it is only people who are unaccustomed to that system who thinks it is somehow unqualified to do that.

        American who lives in a country that uses C now.

        20=frickin cold 30=swampy ass 40=nope

        Not enough degrees of separation

          20 isn’t cold at all, it’s perfectly warm.

          10 is nippy, but you still warm up quick after a few minutes walking, and get sweaty if you’re working on something.

          0 is cold enough for a couple layers. Jumper + jacket so you can take one off if you warm up too much.

          -10 doesn’t feel that much different to 0.

          -20 is time to put on a thicker coat over the jumper.
