    I just use

    30°C is hot, 20°C is nice 10°C is cold, 0°C is ice.

    Obviously that won’t apply everywhere, but in milder climates it works pretty good.

      And 40°C is the melting point of the human brain.

      Which goes some way towards explaining some of the decisions happening in Florida, Texas and Arizona during their ridiculously hot summers…

        I understand and appreciate your joke, but is it really? And I imagine that the bones and skin would melt first, right? Idk. I’ve never considered that someone could melt from the inside.

          Not literally, no, but it can be very difficult to concentrate on anything else when you’re suffering under immense heat and a lack of concentration can lead to a figurative brain meltdown.

          That being said, the brain is mostly fluid, fat and electric connections so it would DEFINITELY melt long before your bones.

          Would have to be around 50-60°C for the 60% of it that’s fat to hypothetically melt if exposed directly to the heat rather than protected by the skull and cooled down by the blood, but that’s nothing compared to the 1670°C melting point of human bones.

          Btw, I hope you’re happy with this reply since my Google search history looks rather grisly now 😂

    For the other Americans that came into the thread hoping to see a conversion:

    • 10c = 50f
    • 30c = 86f

    Edit: I’d like to note that 10c is a very reasonable temperature for shorts. I’m a Minnesotan (basically Canada lite (please annex us)), people start raising eyebrows at around 0C

      0C? Fellow Minnesotan here and I’ve definitely seen plent of people wearing shorts at temps below -5C. But I’m also in a college town so that may change things.

        I once amusedly watched girls sunbathe in bikinis at St. Lawrence University with patches of snow nearby in, I think March.

        Conversely, I personally wore shorts and a tee one fine vacation in Florida around Christmas. It was 60f, and everybody was running around in jackets looking like they were in Chicago in January.

      The quick conversation I use is take off 30 and half the rest to go F to C or double it and add 30 to go C to F.

      20C doubled is 40 and add 30. 70F

      80F take off 30 is 50. Half that is 25. 25C

      It’s not completely accurate but close enough for conversation purposes.

    Jokes on you. I’m an american who works with scientific equipment so I mainly work in Celsius. Also live in Minnesota so we get the best of both worlds. Last winter hit almost -30C at times meanwhile tomorrow has a high of 39C with almost 70% humidity.

    I don’t know if they stopped, but American kids at least used to be taught both Celsius and Fahrenheit. At least in some parts anyway. I was taught both as a kid, with my school largely banning the use of Fahrenheit by staff on campus even, for instance.

    I was taught both.

    Just like I was taught both metric and imperial.

    I use both temp scales, though fahrenheit is more common.

    I use both measurements scales, though imperial is more common.

    One thing I’ve never understood though. Metric is more precise for measurements (at least without needing to involve fractional measures). I totally get why it’s superior for a lot of things, and indeed it is used in many places for this exact reason.

    Why would anyone say Celsius is better? Apart from freezing and boiling temps seeming somewhat arbitrary with fahrenheit, does it not allow for much higher precision with regards to temperature identification without resorting to decimals? Isn’t this the same rationale used with metric vs imperial? It seems like a double standard to me, because remembering two temperatures (for boiling and freezing) seems like a small price to pay for a more precise system.

      Because precision has nothing to do with it and it’s all about being easy to convert between different units and having sensible zero and 100-points for temperature?

        How often do you convert temperature to different units? Isn’t that what we are stupid for doing?

        And I would like to know why precision is irrelevant for temperature but relevant for other things.

        I’m being genuine, I’m not trying to shit on you. I’m pretty open about liking the metric system, and I think the reason we don’t use it is largely the extreme administrative costs of doing so more than anyone thinking imperial is actually better. I think most agree it’s pretty clearly worse.

        But I legitimately don’t understand how people can argue Celsius over fahrenheit when the arguments for fahrenheit largely match those for the metric system.

          How often do you convert temperature to different units? Isn’t that what we are stupid for doing?

          I was talking about Metric as a whole, where the units of measurement for distance, mass, etc. are easily convertible and the unit for temperature has sensible zero- and 100-points. I would have thought that was obvious.

            Why would you talk about metric as a whole in response to a question asking about Celsius in particular? I very openly stated that I understand why metric in general is used for measurements of length, weight, and volume and asked specifically why people argue that Celsius is superior when its weaknesses in comparison to fahrenheit are similar to imperial’s weaknesses in comparison to metric.

            I would have thought that was obvious.

        Fahrenheit has a fairly sensible 0 - just as Celsius is the temp of ice water, Fahrenheit is the temp of salty ice water.

      Celsius is better because it’s the standard used by almost the entire world. If you’re talking with anyone but Americans or you’re working in science then you’re using Celsius.

      The rest is just arbitrary - you can get used to either system.

          That’s not at all what I’m saying. I’m saying there’s little to no difference in practical use, except for the convenience of using a standard. Standards make life much easier because you’re talking the same language as everyone else. When you’re pretty much the only country still using Fahrenheit maybe it’s time to think about using the global standard?

    Double Celsius and add 30. It’ll get you close enough for environment temps.

    10*2 is 20, plus 30 = 50.

    (10°C × 9/5) + 32 = 50°F

    30 doubled is 60, plus 30 is 90.

    (30°C × 9/5) + 32 = 86°F

    10°C is mild af. Who tf doesn’t wear shorts when it’s 50F?

    If you want to sound more metal, tell people how cold it is in celsius. Was it kinda cold or was it in the negatives?
