    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 😂

      It’s the best way to think about it because if you’re always doing the calculation in your head you still always think in Fahrenheit first. Just get the feeling for Celcius instead of trying to shoehorn a worse system in (as a user of said worse system myself).

        Don’t Texans just stay in air-conditioned buildings and vehicles all the time? I just saw a YouTube video where a guy in Texas was complaining that his air conditioning setup wouldn’t get the temperature below 76°F, which I found odd since I set the thermostat on my AC to 26°C (which is nearly 79°F.)

          Yeah that’s absolutely a thing all over warm weather states in America. It drives me crazy that I try to acclimate to the higher heat and just end up inside with 68° air conditioner settings. Absolutely freezing my ass off. But the reality is that is more middle/ upper class living. If you’re doing manual labor or living in poverty, you know what the heat is actually like.

    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

        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.

            Because it’s a massive waste of money for little to no benefit, and barely actually comes up because unit conversion is trivial and is done constantly regardless of overall unit system.

            Armchair unit system fanatics make it out to be such a bigger deal than it is. Whether im working in metric or standard I’m doing several to several dozen dimensional analyses anyway, normally with industry specific units. Which again, exist in both standard and si.

        If you grow up in the US, you learn both systems and you’re able to convert between them. It’s easy.

        2.2 pounds to the kg

        1 inch is 25.4 mm

        A gallon is 3.8 liters

        But it’s fun watching supposedly intelligent people from other countries who reeeeeee when seeing imperial units.

          ? i don’t know about you, but multiplying 19" times 25.4 isnt something easy at all to do quickly in your head. Also, not to mention the best example: when i have to convert cm to m I move the comma

          when I have to convert from cm to freedom units: -Divide the height in centimeters by 30.48 and write down the whole number as feet

          -Multiply the decimal part of the above division by 12

          -Round the result of the multiplication to the nearest whole number and write it down as inches

          like, really? you have to use two different units added together for one thing? How is that easy?

          As a Canadian myself, it really depends. Most of us only understand farenheit in certain contexts. Some of us can understand it for weather but I think that’s mostly older generations. I use farenheit for oven and pool temperature only. In every other context, it is meaningless to me.

    Here’s a rough C° primer for Americans

    0° or below, fucking cold

    1° - 10° cold

    11° - 20° cool

    21° - 30° warm

    31° - 40° hot

    41° or above - Jesus Christ I’m on fire!

    As for Fahrenheit for the rest of the world, on a scale from 0 to 100, how hot is it? Assume anything below zero is really fucking cold, and anything above 100 is really fucking hot.

    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.
