  • Lol you edited it, I think, to take out the repetition that it was somehow burdensome and difficult to tell whether it was above or below freezing in Fahrenheit. Like people in Fahrenheit couldn’t tell whether it was going to rain or snow before they did some “math.”

    I’ll take that as a W. Next time I urgently need to know how many degrees below freezing it is, and have forgotten how to subtract, I will contact you and apologize.


  • Is it your impression that I have just never used Celsius in any kind of scientific calculation? I’m not familiar with this advanced technology, because every time we do physics in America we have to break out the 1900s thermometers and slide rules?

    Also you didn’t answer my question about quantifying the computational burden you’re avoiding by not having to compare to 32. I didn’t say it was not significant! In fact, until 1855, the method for such calculations wasn’t even invented yet; people just had no idea what temperatures were freezing or not, and homes had to keep a cup of water next to the thermometer just to add that additional information, so they would know if it was going to snow or rain.

    I just wanted to know. I was just curious how much extra difficulty I am dealing with in my life, without even being aware of it.


  • As opposed to how horribly difficult it is to do with Fahrenheit.

    What length of calculation time would you say is required before someone can tell whether it is going to freeze, or whether it will be snow or rain, when we’re using Fahrenheit? How many years of education are required before someone is able to do the math to do it?

    Honestly I expected the Celsius people to do a better job than this in defending it. There are reasons why it is better (having it fit in with the other SI units in a coherent way for scientific calculation being the best I’ve heard) but this is straight up moon logic.



  • I don’t know if people are old enough to remember this. Back in the 70s, they really made a push in the US to convert the road signs to metric. From time to time they have tried, and people have always resisted. Anyway, in the 70s they studied it, made a commission (which in the end Ronald Reagan destroyed as he did so many other things), and tried again. They started putting sneaky little kilometer signs underneath the mph and “mile 5” and whatever markers, just to get people used to the idea. (They are still around, in some places.)

    Nope. People could see where it was going. America as does some other countries has a proud tradition of shooting holes in road signs with guns. I don’t know why people do this, but when the metric signs came along they shot the shit out of them. I don’t know that the unsustainability of keeping them installed when people kept shooting them into semi-oblivion was part of what made them abandon the idea, but it certainly couldn’t have been good for the morale of the people working on it, and probably it made a difference.

    That is all the good and all the bad of America rolled up into one. The people had spoken. Keep your god damned kilometers. We’re not changing the date for Thanksgiving. It’s not the Gulf of America. Fuck you, I won’t do what you tell me. And so on. Hopefully.






    • 0: Real cold
    • 100: Real hot
    • 200: Low bake
    • 350: Medium bake
    • 450: High bake
    • 1000+: Melts metal, like go wild, that’s about where off the chart starts

    👍

    • -20: Real cold
    • 0: Water freezes, real useful if you need to know that one in your daily life and “32” is too hard to remember
    • 30: Real hot (for some fucking reason)
    • 90: Low bake
    • 150: Medium bake
    • 230: High bake
    • 600+: Melts metal

    😢

    It’s like the exact opposite of distance units. Normally you look at the metric ones and say “thank god! It just makes sense. It’s all tens and it’s logical” and then the imperial is all wacky numbers.

    With Fahrenheit you can say, “How is it outside?” “50s” / “60s” / “70s” / “80s” and it’s instantly a comprehensible answer. Maybe “low 70s” “mid 70s” if you want to be precise and you mean at an exact particular time of day. Meanwhile, the Celsius weather channels are over here putting decimals in their temperature predictions because the units are too unwieldy to even tell people what temperature it’s going to be if they have perfect integer precision. Of course, three significant digits is way too many, so they’re half making up nonsense for the one-tenths place, but they have to do it anyway. Why do they have to? Because they’re using Celsius, like a bunch of chumps.



  • Yes it does.

    Fahrenheit decided that we should use a scale based on what humans feel like is the full range of sensible temperatures, with that range set to 0 through 100.

    Celsius decided that we should use a scale based on what liquid water feels like is the full range of sensible temperatures, with that range set to 0 through 100.

    Kelvin decided that we should use a scale based on what atoms feel like is the the full range of sensible temperatures, with that range set to 0 through NaN (exception thrown).

    So, chemists the world over like to use one of a couple of different scales depending on whether they are primarily concerned with the world defined by water, or the world defined by atoms, because it’s convenient to use scales that are generally aligned with the feelings and behaviors of the entities you are concerned with.

    And then sometimes humans come into the room, and say hey those are cool but also I’d like to use a scale that is generally aligned with the feelings and behaviors of humans, and for some reason everyone in this thread falls down on the ground and starts screaming and wailing, saying they are wrong and stupid for wanting to do that.



  • I don’t know about you but I do not only use temperature in order to know … if outside is cold or not

    Yeah what maniac would care about something like that

    I usually use temperature scales in order to know if my computer is hot, my car/bike engine, my food

    Oh, I see, the things that everyone uses temperature for all the time. Perfect sense.

    I like to know if my food is freezed or is boling

    You all are doing a terrible job of selling me on Celsius here.



  • during the summer, peeps would not say:

    Perfect weather, two hundred and ninety six degrees, slow breeze and scattered clouds!

    They would probably shorten it to:

    Perfect weather, ninety six degrees, slow breeze and scattered clouds

    You’ve almost got it! Now talk about the opposite problem where all the temperatures are at weird low values and 0 is in the wrong place
