    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 😂

        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.

    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.

      Its currently 110F. Aka, hot.

      Or, -28c to 46C. Currently 43C. And 40% humidity. Feels horrible.

    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.

      I’ve always thought Fahrenheit was the better measurement in regards to weather. 0 F is uncomfortably cold, 100 F is uncomfortably hot. It makes so much sense for the weather. 0 C is freezing, 100 C you are dead. Of course, for most things Celsius makes more sense, and even though I live in the US I don’t even know how to measure computer temperatures in F, it just sounds crazy. When it comes to weather though? Fahrenheit is where it is, in my opinion.

      Please guys, I know plenty of you will disagree with me, that’s okay, this is just my opinion. Please don’t get upset I know metric is generally better!

        I always found fahrenheit a lot more arbitrary: in Celsius 0 is the freezing of water, so if you are driving/walking, that is a very important temperature to look out for. Also 30 being hot or 100 being hot outside does not really make a difference. Some people find 30 hot, some other find it OK, since its subjective anyway

          Water freezes at 0°C at standard pressure, sea level.

          If you are above or below, it will be different.

          Saying “It’s not 0°C outside so there’s no ice on the road” is dumb. Because there could definitely be ice on the road.

          You should be looking out for other things while driving. Not if the one thermometer, who knows where, is saying that it’s 0°C or not.

            As usual, there should be a bit of flexibility in there. I am not saying “oh, it’s 0C, therefore ALL water in all town is frozen , lets wait until it gets to 1C so all water melt”. But more on the line “oh, its around 0C (+ or - 5C), lets be careful while driving because some of the streets might have ice”. Farenheit freezing temp is 32 I think? Thats VERY arbitrary. A lot more than C.

              • or - 5°C

              23°F to 41°F is -5°C to 5°C

              If it’s below 40°F I’d be cautious of Ice. Once again, it doesn’t matter that water freezes at exactly 32°F at standard pressure.

              It’s like boiling water. No one puts a thermometer in water to make sure that it hits 100°C exactly.

              150°F water will scald you in a second (65°C)

              140°F water will scaled you in 3 seconds (60°C)

              120°F water will scaled you in 10 minutes (50°C)

              +100°F water has the potential to scaled you (~40°C)

              I’d rather know that +100°F water has a chance to burn me than remembering +40°C has a chance.

              That’s way more important knowledge than the freezing and boiling temperatures of water at standard pressure.

        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.

            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.

            Why on earth would I think that? I made the comparison to other units of measurement to demonstrate why smaller units are useful in some cases. There are cases where its not useful, but there are also many cases where the advantages of Celsius aren’t useful. Neither is inherently better, the correct one to use is the one you know better or the one that fits the use case better.

            In fairness to Fahrenheit, you can round it to a whole number with a lesser difference in feel. That’s more for feel though, for measurements of temp in cooking or chemistry, Celsius is useful due to boiling point.

                I was more thinking of when you’re telling your friend what the temperature is outside, or scenarios similar to that. It’s not useful in most other applications.

                  What difference does it make if the temperature is 79 or 80 F? That’s a difference of about half a Celsius, and as a Celsius user, I can tell you that I don’t plan my daily life based on a half a degree difference, or even a one degree difference; 5 degree precision is almost always enough.

      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?
