    Celsius is the perfect system to describe how hot or cold it is, assuming you’re a water molecule.

    You guys are too ignorant to see how full of shit OP is.

    50F is not 50% hot, it’s cold. If your house was 50F you’d be saying “something is wrong with my HVAC”. You’d never heat to only 50, and you’d never cool that far. It’s cellar temperature (colder than a wine cellar, warmer than a root cellar).

    70F is 50% hot. It’s a temp you’d cool to in the summer, and a temp you’d heat to in the winter.

    100F isn’t 100% hot either, most people enjoy a hottub to be a little hotter.

    Tldr: OP is wrong

    100% hot would leave the measured medium superheated and possibly fissioned… so a measurement scale more extreme then kelvin

    I would prefer Celsius if it was smaller degrees, so 0 = freezing is great logic but boiling needs to be 1000 not 100. There just aren’t enough degrees between freezing and boiling, Celsius is too inexact.

    And no way is 50 medium in F, it is cold. We might actually put the heater that low because the HVAC system we have is built more for cooling, but that is very, very cold feeling. 0 in F is beyond cold, that is 32 degrees (or 18 of your civilized degrees) below freezing. Hellish cold.

    Just in case because this is the internet at the end of the day. Fahrenheit is not linked to a percentage of anything. It’s mostly arbitrary in terms of assigning a number scale to temperature and it’s linked to brine solutions and human body temperature.

    Hot take: the best temperature scale would have 0º be water freeze point and 100º be human body temp. Fahrenheit is already supposed to be that but nobody gives a shit about a saline solution freeze point and they fucked up the human body temp.

      0 °F is pretty close to the freezing point of salt water. So close I always wonder if that “saline solution” was just salt and water.

      I propose the body temperature of an average opossum as the fixed point for 100 because they are cute as heck. We shall call this unit Possigrade. And anything above 100 Possigrade should be called the ‘rabies zone’ and 0 Possigrade should correspond to 8°C, as this feels very cold when dressed inappropriately. In addition, there is now the Bakers Possigrade, where 100 corresponds to 27°C, as this is the temperature at which sourdough bread rises by about ⅓ in 5.5 hours.

      But seriously: Celsius is fine. On Earth, we are primarily interested in water at atmospheric pressure. Too many things contain water (pipes, food, paint, etc) and they react differently at 0 °C than at 4 °C. For this reason, we deliberately avoid using water in applications that are regularly exposed to sub-zero temperatures. Water is simply everywhere, so 0 °C and 100 °C are important tipping points for general use.

        Celsius is great for engineering because Things Happen™️ when water starts boiling or freezing. But most people aren’t engineering daily. Cooking temps generally dont require much precision and there are too many niche break points to easily factor: safe meat temps, refrigeration temps, oil smoke points, Maillard reaction, etc… Our chefs are basically screwed no matter what.

        That leaves measuring weather as the most universal daily application. Celsius is not great because the temp outside your door is going to be between mid -20º and mid 40º. It’s nice to have water freezing at 0º (snow, frost, ice) but thats the only interesting break point. You could just as easily set 100º to be the temperature of the sun and have the same daily experience.

        Humans are endothermic, which means being somewhere hotter than us is Not Good™️. That would be very nice to set as a breaking point for weather purposes, but unfortunately the danger varies wildly with humidity/airflow/personal tempature regulation/hydration/etc… If we set the triple digit break to indicate an unsafe body temp then we at least can approximate the danger and get a little bonus medical utility.

        Mean body temp varies slightly based on several factors:

        So set 100º to be one standard deviation over and its perfect for daily use. Checkmate Celciusts

          Celsius is great for engineering because Things Happen™️ when water starts boiling or freezing. But most people aren’t engineering daily.

          I’d argue that it’s more covenient to use a common scale for all applications of the same measurement than to have multiple different scales, just because that would eliminate all conversion concerns. Someone I know is in engineering school has switched entirely to using °C simply because that’s what they deal with at school anyway, to the point they don’t even write °C anymore in casual chats.

          For other applications, it seems like the scales we’re used to are more or less arbitrary anyway, so that’s really just a matter of getting used to it. Some are used to calling ~70°F room temperature, others say ~20°C,

          So if it matters for one case, but not so much for others, and we were to pick a single scale, I should think it would be ideal to go with the case where it does matter.

          Or we just keep doing this thing where people use what they’re used to and we just quickly look it up or someone comments with the conversion and move on with our lives.

          Humans are endothermic, which means being somewhere hotter than us is Not Good™️.

          Endothermic refers to the ability of the organism to regulate it’s temperature, not just the ability to generate heat, but also to cool itself down. We humans are so good at it, that we can literally just jog prey down in hot environments and pretty much all animals will overheat before we do.

          Hell, in my apartment there’s a room especially for making it very hot and humid. Even above 100c, and I still don’t boil. Weird, huh?

          cooking temps generally don’t require much prevision

          Alright. Sure. Yeah. Why not. /s

          Perrsonally I set 100° Egg (or 100°E) to equal 180°F because that’s how much i want to heat my egg when i am making ice cream. Gets you a good, custardy base for your ice cream machine.

          I would also accept °Icecreams or °Is as the units

          zero would be 20°F because that is Ice Cream’s proper storage temperature.

          edit: yeah i think we’re going with °Is

      I think I see what you’re getting at, but you could just memorize 40, 35, or even 30 as “watch out, pretty close to human body temperature”. Three anchors in the scale beats two.

    We need to collectively realize that both Celsius and Fahrenheit are mostly arbitrary and not more than practical conventions to assign numbers to temperatures. Kelvin makes more sense but is impractical for daily use. It’s just US-Americans distracting from the fact that most of their units are objectively bad compared to Metric by pointing out that Celsius is only marginally better.

      No, it’s just in response to the countless number of non Americans who constantly insult Americans because we have a slightly different measurement system that doesn’t effect the insulter in the slightest. It doesn’t help that anyone in the sciences in America do know metric, like fully, no one has a problem using it here and I know plenty of people even outside of the sciences that know enough metric to get by fine, you guys really need to get over your strange obsession with our measurement system.

        I don’t disagree that people venting about F can get overzealous. I still think there’s a significant improvement with C though. Not saying it’ll make American scientists better, I believe you that they do fine with it. But that’s also contingent on the rest of the units being imperial.

        I often see conversion constants with the unit conversion baked into them, so you lose info on what was the empirically derived constant and what’s just there to allow you to multiply temperature in F against other thermo quantities that rely on relation back to Kelvin.

      This is a really bad representation lmao, you’re giving an example of Finland in like mid winter comparing it to the reaction of someone who literally never sees winter. My state has had around -30°c for the last 2 weeks, been chilling, I’ve definitely preferred when it’s been getting closer to -20 to -10 which has been funny, actually enjoying temperatures under freezing, but I don’t get what your comments trying to say. It’s not like Finland is that temperature all year lol, the climate of my city is surprisingly similar to a lot of Finland and I gotta say being in the cold still sucks.
