    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).

          Austin is the common “island of sanity” that happens with American cities. Is it enough to say in Texas… Not for me.

      • 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.

      More like 30° I’m melted into the pavement, 20° warm but good, 10° is near perfect, 0° starts getting cols, -10° put on a jacket, -20° and below put on a good jacket.

      • It doesn’t fit into the rhyme, but -10°C is the point where just wearing a coat isn’t enough. You need to either start limiting the time you spend outside or put some serious thought into the protective clothing you wear beyond just throwing a coat on as you go out the door.

          I had a water bottle in my car when it was around -11 °C, and when I tried to drink it, the supercooled water instantly froze solid, which was startling, but hardly surprising.

    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

            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.

    • I was going to make the joke that Minnesotan kids definitely know what -40°C is.

    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.

        Because for weather, °F is arguably better. 0°F - 100°F is the general range that most weather on the planet happens at (yes I know there are extremes where it gets to like -30°F or 120°F, but bear* with me). You can then further break those up into 10°F segments that are a bit more practical and granular than 10°C segments:

        • under 0°F: stay inside
        • 0°F - 10°F: really fucking cold, don’t stay out too long or you risk hypothermia
        • 10°F - 20°F: still really cold, but you can stay out long enough to shovel your driveway without fear of losing fingers/toes, if you’re wearing winter gear
        • 20°F - 30°F: cold but not bitterly so. Perfect weather for outdoor winter activities like sledding or snowball fights
        • 30°F - 40°F: Snow starts melting here, and you can probably ditch the scarf, but you still need a winter jacket
        • 40°F - 50°F: Too warm for your heavy winter jacket, to cold for your light spring jacket. It’s layering season baybee
        • 50°F - 60°F: still layering season, but you can probably get by with just a light jacket at this point, especially if you’re doing something active outside. Some people start breaking out the shorts, but that’s not the norm.
        • 60°F - 70°F: a more generally acceptable range to start wearing shorts and short sleeves. Perfect temps for doing yard work and sipping beers on the patio alike
        • 70°F - 80°F: definitely shorts weather, and pools start coming into play. If you’re doing something rigorous outside, you’re probably sweating
        • 80°F - 90°F: you’d probably rather be inside, if you’re not in a pool. You’ll be sweating just lounging in your deck chair.
        • 90°F - 100°F: hot as balls, probably not worth going outside for very long, as the pool water feels like taking a dip in lukewarm soup
        • Over 100°F: stay inside

        Now I know you can do something similar with °C, but the workable range there is smaller, because you’re going from like -15°C to 40°C. It’s less granular, and the start/stop temps are more awkward.

        Is it weird that water freezes at 32°F and boils at 212°F? Sure, absolutely. When you’re doing stuff in that context, it absolutely makes sense to use Celsius, where you’re working on a nice, neat 0°C-100°C range. But weather, the thing most people contextualize temperatures with, doesn’t happen in that range. It starts well below freezing, and (hopefully) doesn’t get anywhere close to the boiling point of water. For that, I’d argue °F is actually a little more useful.

        Because it doesn’t have as much resolution as Fahrenheit.

        There are 180 degrees between freezing water and boiling water in °F. But 100 degrees between the two in °C. So with Fahrenheit we can give mote accurate temperature info without resorting to decimal degrees. And if your response is “learn to handle decimals” then the same argument can be given for inches vs mm.

      It’s taught but not really for weather. So while I know the boiling and freezing points of various substances in Celsius, I don’t have instant recognition when I hear a Celsius temperature, I have to convert it in my head.

        No need to convert. 0 to 40 is the part of the scale for weather, where 0 is dangerously cold and 40 is dangerously hot.

          No need to convert? What do you mean? Are you saying if I just intrinsically knew Celsius for weather I wouldn’t have to convert Celsius? Because that’s obviously true, but I’m just explaining I don’t intrinsically know Celsius in that way.

          Also, even if I did get to know Celsius really well, I would still have to convert it every time someone uses Fahrenheit, which is pretty much all the time in the US.

          Lastly, what do you mean, 0 C is “dangerously cold”? Where I live the temperature stays below 0 C for long periods of time, never going above it.

            If you know those two numbers, 0 and 40, you can get a general idea of what the temperature is in Celsius without doing any math. If you hear 20, you know that’s a moderate temperature because it’s right in between. If you hear 30, you know that’s fairly warm. Below 0 or above 40 are extreme cold and extreme heat, respectively.
