    Pedantry:

    K and °R at agree on 0 K and °C agree on the unit difference °F and °R agree on the unit difference °R and °Ra are the exact same thing (??)

    source
    • Zagorath@aussie.zone ⁨7⁩ ⁨months⁩ ago

      Also Rankine, being an absolute scale, theoretically shouldn’t be in ° anything, and it’s only some weird historical quirk that is the reason it usually is called degrees.

      source
      • Eatspancakes84@lemmy.world ⁨7⁩ ⁨months⁩ ago

        I am not sure I follow that. The scale is always relative right? It’s just the zero that’s absolute. But that’s also the case with measuring angles where we do use the degree symbol.

        This screenshot is a little bit hard to see, but from what I can tell:

        °RA is pointing at °R and °C
        °C is pointing at K and °F
        K is pointing at °R and at °F
        °R is pointing at °F (and the other gun isn’t aimed at anyone in particular)
        °F is pointing at K and at °C

        Emphasis disproves your claims, sadly. Perhaps there was another way to label them to make it fit, but that’s not what was done here.

    I went down a huge rabbit hole cause of this. I personally like °F over °C but agree it’s arbitrary. So I tried to make a scale that started at the coldest air temp on earth (some day in Antarctica) and went to the hottest day on earth (some day in death valley) and put the coldest day at 0°A and the hottest at 100°A.

    Sadly this made a scale that was less precise than I’d like. I like that I can feel the difference between 73°F and 74°F and don’t want to have to use decimals.

    So maybe the end points could be only places where people actually live. Well it looks like some people live in Russia around -70°C and some people live in northern Africa around 50°C so if you just take °C and add 60 you can get a -10 to 110 scale where most temps would fall between 0 and 100. Still has the unit difference of °C (which I don’t like) but I like that most temps are between 0 and 100. I also don’t really like negative temperature since it seems wonky.

    To “fix” the unit scale you could just multiply everything by 2 so the difference between each full degree is half as much. So temps would be between -20 and 220. °A = 2(°C + 60) °A = 2(°C) + 120

    And it turns out I (basically) created the Fahrenheit scale but moved. °F= 1.8(°C) + 32

    TL;DR: I’m stupid and this was fun but also a waste of time lol

      Celsius is tied to points of of ice melting and water vaporising. Since water is very important for the life on our planet, it makes even more sense that arbitrary chosen meters or seconds.

        And similarly, Fahrenheit seems to be tied to the internal temperature of the human body, with 100 degrees being the maximum that the average person can handle before their organs start to be damaged.

      • untorquer@lemmy.world ⁨7⁩ ⁨months⁩ ago

        Once you’re below -6C or so you just need more insulation. -6C to 10C in many ways can be harder to manage due to humidity, especially in wet conditions. My prolonged exposure experience is only down to -30C. I did not have enough insulation, but an extra base layer, better gloves/boots would have been sufficient. I was fine with fairly light clothing down to -18C. I hear -50C is where it starts to get really harsh again.

        Your body also adjusts a lot. In the Summer in wearing a puffy indoors at 10C(50F) but in the winter I’ll go out in a t-shirt at -10C, especially if doing manual labor.

      It’s the Rankine. Some Scottish dude wanted to use Kelvin without using Kelvin. It’s basically the Fahrenheit scale but with 0˚R set at absolute zero.

      0˚R = 0K 1˚R = 0K + 1˚F

    Celsius tried to fit too much into 100 notches to please big math.

    F is more nuanced with more notches, but the ends aren’t logical. It coukd be shifted perhaps, but how?

    If freezing was moved to 0, then water boiling would be 180

    Perhaps C could have had a 200 degree range, then it would be closer to F and not so hard to convert.

    But also: Scientists are important and we shouldn’t make it too easy, it demeans their work. Maybe make the C scale show water boiling at 183.4521 degrees so scientific calculations are more impressive-looking and respectable.

      The SI unit scales are chosen to fit together to avoid “respectable” scientific calculations.

      To heat one milliliter (1 ml) of water one degree Celsius (1 °C) you need one calorie (1 cal) of energy.

      Also the dimensions of one milliliter, is one cubic centimeter (1 cm^3), and that amount of water weighs 1 gram (1 g).

      Thus 1 liter of water needs 1 kcal of energy to heat up 1 °C.

        I’m aware, taught that in school.

        Also aware of the real world, those things don’t mesh the same at altitude.

        In theory, reality and theory are the same. In reality, they’re not.
