      Change is hard. In Europe we wanted to drop daylight saving time, but nobody could agree on which hour to keep. So it’s here to stay. Sigh.

      Only if you’re measuring water temps. In general it makes more sense to put the zero of your scale at absolute zero

      Fahrenheit’s 0 is the freezing point of water - salt water that is. Not that I think it’s better, just that there was some thought put into it.

        It… isn’t. That would change wildly depending on which sea/ocean you get your saltwater from (more salt = colder freezing point).

        It really is defined relative to a very specific brine mixture (in the most scientifically generous origin story - some say he literally just measured the coldest winter day he could). Well except it isn’t anyway, because like all US units nowadays it’s defined against metric units (namely the Kelvin, just like 0°C is actually defined to be 273.15 K).

    I live in the United States and although I grew up here using Fahrenheit, I switched to Celsius almost 10 years ago. Part of my reason for switching was the rest of the world was using Celsius and every time they would mention the temperature, I had no clue if that was very hot, or just right and kept having to convert, so since there were not that many countries that used Fahrenheit, I switched. I still know what the comfortable range is in Fahrenheit, but now I also know in Celsius as I use it every day. Also, I no longer appear to be an old curmudgeon that is resistant to using a system the rest of the world already uses.

    I had once heard described that fahrenheit’s best feature is that you can go “oh, 1-100, ‘sheesh, that’s really cold!’ to ‘hoof, that’s pretty hot!’” and yeah, while I was in the US where most temperatures (RIP Florida) change all the time, that sure was convenient.

    However, living in a country that always stays in the 80-100 range, the ‘oh fuck, the water’s freezingto 'oh fuck, the heat death of the sun is upon us’ range is a MUCH more useful scale to knowing if we’ve been struck by some sort of apocalyptic event today

    I like to refer to them as Freedom units and Communist units (in jest, obviously). I will say, though, that Fahrenheit feels like a more precise scale for measuring temperature even if the units are goofy.

      What additional arguments besides personal experience would you give to back this precision claim?

      Temperature scales are arbitrary by nature, and the criteria behind their definition can be useful or not. Fahrenheit’s isn’t that much useful compared to Celsius’ or Kelvin’s.

        I’m not arguing on Fahrenheit’s behalf or saying it IS more precise. I just said it “feels” more precise because you have finer increments in whole numbers. 70 degrees F is about 21 degrees C while 90 degrees F is about 32 degrees. 20 degrees of increment in F versus 12 in C which feels more precise. It’s the same way metric length measurements feel more precise because there are whole number millimeters rather than fractional inches.

        I have no strong opinion any one way, other than I feel like everyone should endeavor to be comfortable converting between various systems of measurement.

          You can simply use as many decimals you want to make Celsius more precise. You don’t see it used in general because it really isn’t needed.

            The little digital thermometers I have around the house read to one decimal place. The precision argument is just bizarre.

        The range for livable temperatures follows a more reasonable scale. Hot is really high numbers. Cold is low. The exact temperature is more precise because the range is larger.
        Celsius is fine for scientists but for the regular person Fahrenheit has a better range.
        Also I’m biased.

        • I’m also biased.

          But:

          • Celsius is easy to understand, even for children: water freezes at 0°C, boils at 100°C.
          • It is understood by more people in the world.
          • If the US used Celsius, understanding scientific papers and data would be easier for common people.
          • In Celsius, the range of livable temperatures for humans (-20 to 40°C) still gives plenty of precision. Additionally, each step in the Celsius scale corresponds to a bigger change in “feel” of the temperature, which leads to a more intuitive understanding of temperature changes.

                As someone who uses their thermostat and regularly switches between 72 and 75, yes. Yes I can.

                  Fake thermostats which exist solely to give the occupants of office buildings an illusion of control are an entire product category. If I were to replace your thermostat with one without your knowledge, you would be just as happy turning it up and down all day.

    F is kinda nice for weather as a scale of 1 to 100 of really cold feeling to really hot feeling. But for anything scientific or calibration related, C is great

      Disagree. Celsius is super helpful for determining if it’s gonna snow or not, a key weather thing where I live. Humid and cold and below 0? Snow. Humid and cold and above 0? Rain or freezing rain.

      Also helps with plants. Below 0? Frost.

      I’d argue you can’t get more intuitive than 0 is cold, below 0 is very cold. Celsius also plays nice with round numbers, every 5 or 10 degrees is a change in feeling. 0 is cold, 5 out is cooler, 10 out is cool, 15 is moderate, 20 is comfortable, 25 is room and warm, 30 is hot, 35+ is very hot. Every ten degrees we’re doing big changes. 0 is frozen, 10 is cool, 20 is comfortable, 30 is hot. 32 being frozen doesn’t feel as intuitive.

    As someone who moved to the US later in life, I learned to use fahrenheit because there’s no way to talk to anyone about the weather or cooking otherwise.

    If you need to do the same one day, don’t bother trying to convert in your head. Just learn the numbers conversationally. Familiarize yourself with how the weather feels with the number the weather app shows.

    I can’t convert at all but I can use both C and F in conversation because one rarely needs exact numbers anyway. You learn the ballparks pretty quick.

      This, for sure. I live in the US and wanted to learn to understand Celsius so I switched my phone to use it. Internalizing a system works where translating/converting does not. I quickly learned that I feel comfortable in temperatures in the 20s. Since I feel comfortable in Fahrenheit temps in the upper 60s to mid 70s I can guess what the conversion is for most temps, but I don’t have to do it to understand that I like how 22 C feels.

      Similarly, if you’re traveling and having to use a foreign currency I prefer to establish an idea in my head of cheap, reasonable, expensive than stopping to convert every price exactly. A “reasonable price” is relative to the item and location, of course, and should also affect my perspective.

      Absorbing a new system by this method works fairly easily for temperatures and money, but less so for other measurements. I don’t have as fine-tuned a sense of what ounces, pounds, or grams feel like as I do units of temperature. And I am always adding or subtracting 12 to understand time when expressed as 13h and up.

      During the brief period when the US was encouraging metric system understanding there were many highway speed limit signs expressed as 55 mph / 88 kph. Every time I need to make that conversion I think of 5/8 because of that sign. And I usually just make guesstimates that work well enough.

      I like learning new things. The generation before me in my family turned off their brains long ago and now suffer dementia. I work to keep my mind active. Learning other units of measure is one example.

      Finally I’ll say that I WISH I could get to a point of understanding languages this way without translation.

        FWIW Fahrenheit has more precision for the temperatures you most commonly feel. Day-to-day you’re likely to feel temps between 10-32°C (range of 22°), which is 50-90°F (range of 40°). It might not seem like a big deal, but I can tell a difference in my house when setting my thermostat from 68°F to 69°F; conversely, if I turn my thermostat to C mode both values get rounded to 20.

        But yes, as an American, I think of CPU temps in terms of C, I know water freezes at 0°C/32°F, I know water boils at 100°C but have never committed to memory what it is in F, and in chem classes we always use C/K.

    Fahrenheit is better for weather, and I’ll fight anyone about it.

    We use Celsius in the lab because it makes math easier, it’s great.

    But Fahrenheit is basically a 0-100 scale of how hot it is outside and that makes perfect sense for describing outside conditions relative to human sensory perception.
