In my new scale, °X, 0 is Earths’ record lowest surface temperature, 50 is the global average, and 100 is the record highest, with a linear scale between each point and adjustment every year as needed.

    I am very surprised that Rankine gets such a high cursedness score. Isn’t it just the same as Kelvin but based on Fahrenheit instead of Celsius?

        Yeah, well that’s a cultural thing really. Celcius and fahrenheit scales are both quite arbitrary. The kelvin scale uses absolute zero, which totally makes sense, but the other fixed point is pretty arbitrary when you think of it. The fahrenheit scale makes sense for the human experience of weather, while the celcius scale makes sense for generally life on Earth where water plays an important role. Neither of them are particularly universal, and they both suck in their unique ways.

        (Edit)

        Life Pro Tip: If you take the piss out of two units at the same time, you can make everyone equally angry.

          Technically they arr arbitrary yes, but sometimes some arbitrary makes more sense than others. Why is fahrenheit 0 at -32°C? Accordinfmg to wikipedia he chose 0°F as the melting point of water and ammonium chloride (what percentage of solution?) and the highest was initially “the average of the hottest temperature of a healthy man”. Do you see why this feels more arbitrady then " the melting and boiling point of water at 101.300 Pa"? Not only these points are constant and measurable, but water is such ubiqutous in human life that it feels at least less arbitrary as a reference point.

          Historically, it was ok. Now it just doesn’t make much sense, sincd we tried (and mostly succeded) to standardize measurements units for centuries (and make them all base 10)

            I don’t really use the Fahrenheit scale for anything, but when I bump into it, I prefer to think of those values as: 0°F is a cold winter and 100°F is a hot summer weather. Makes sense for the human experience, which makes it a very practical unit. The original definition was more technical than that, but it was also severely limited by the technology at the time, so it had some flaws.

            You also have to look at these units in the proper historical context. Measurements were a complete mess, so having at least something that sort of makes some sense and is somewhat repeatable, is a clear improvement. Both, Fahrenheit and Celcius scales totally addressed those concerns, and that makes them both good enough. Absolute zero and plank temperature weren’t even known back then, so what can you expect.

            When it comes to using these units in serious scientific and engineering applications, you run into problems, but the kelvin scale addresses those pretty well. It’s not exactly elegant, but at least it’s functional. Because of historical baggage, we’re pretty much stuck with these units, but it could be worse.

              I agree, historically they make sense, but times have evolved and I honestlt believe certain things should belong to the past, just like we abandoned 12 base monetary and measurement systems, except for a single place on earth that just ignores what everyone else does and goes their own way.

              In a global world, we should unite things instead of dividing for ideological/political reasons. Still, my own is an ideological reason why the imperial system should disappear, but there are pratical issues it causes, espeically when used internationally in industrial and scientific fields, which is very common.

                I mean the imperial system has it’s niche uses too. Fractional measurements are helpful if you’re doing multiple of something and you don’t want to calculate. What if you have 16 boards and you need to lay them out across 19 feet, what’s the width for each board and gap? Well its 19/16 or 1-3/16. And you could say your tolerance is ±1/16. Versus a decimal system, you need to hit 1.1875, with a ±0.0625 tolerance. Yeah no, imperial is better in that case.

                Bur imperial does have it’s pains, especially once you start working with anything that isn’t a multiple of 2. Just wanted to point out it does have some uses.

                I think a large portion of it is that governments/institutions/whatever don’t want to pay the large amount of money it would take to replace all signage/software/etc.

                I think it’s about time we switched to using seconds as the universal time unit. I really hate the messy base 60 conversions we inherited from the Babylonians. Also, month is such a broken unit, and it just makes many calculations unnecessarily complicated.

              0 is an extremely cold winter. Like you’re going to die very quickly if you’re outside without extreme weather gear.

              Where I’m at, mid east coast, we only have a few days each winter get below 20, which is already hellishly cold.

                In the Middle East, the winters are brutally cold and the locals suffer. Tourists from colder regions come there to enjoy their winter vacation in December or January, because it’s paradoxically quite warm. They only pack their normal spring clothes because it isn’t really that cold in their opinion. You know, a thin coat, maybe a thin summer beanie. You’ll probably be ok without any mittens. Also, you can wear normal shoes which is nice.

                Extreme weather gear is considered just normal winter clothes in some parts of the world.

                Yeah well obviously wasn’t planned for a global scale and you can thank European mindset 300 years ago for that so it is definitely scaled for arable land in higher latitudes.

                It wasn’t very technical cause I mean they just weren’t back then. Heck ask a baker what a pinch is.

                But for trying to come up with a scale to give people a way to talk about the temperature in Poland was the point and it’s just stuck for people that are using it same as those using other methods. It wasn’t and isn’t about you.

        Converting between Kelvin and Celsius is simple addition; converting between Rankine and Fahrenheit is simple addition. Converting between the two groups requires multiplication, and pre calculator, that’s notably harder.

        Also, all your kJ/kg/°C or BTU/lb/°F tables and factors are identical when you swap to referencing absolute zero. If you change to the other unit system, all that goes out the window.

    After joking about this at work, I landed on the most cursed scale I could think of… pT = log10 FPW.

    Pros: no bottom to scale, increasing negative values asymptotically approach absolute zero. Water freezes at zero.

    1 pT is almost exactly the melting point of iridium. Lightning bolts are around 2 pT. Boiling points of neon and helium are in the neighborhood of -1 and -2.

      At least that follows some mathematical logic. Mohs scale of hardness is pretty close to pT scale in that sense, but there’s no mathematics or logic involved. It’s just a list of standard materials that define specific points on the scale. When you compare the results with a more logical scale, it looks neatly non-linar at first glance, but the closer you look, the less sense it makes. It’s just a list of exceptions to whatever rule you may have had in mind.

      Doesn’t mean it’s a useless scale. You can totally use it for qualitative assessment of hardness, but steer clear of it when numbers and decimals actually matter.

      You could totally make an extra cursed temperature scale. Randall proposed the °X scale, but maybe we can do better than that. That was pretty cursed because it defines three points based on statistics observed on of Earth and uses linear interpolation to connect the dots.

      I propose an extra cursed system that uses completely fictional values. Let’s take -π as the melting point of unicorns and +GrahamsNumber as the peak temperature in the core of the hypothetical planet Vulcan. Between the two points you can fit any seventh degree polynomial you like in order to get the values that fit your needs. On Wednesdays you can use a sine wave too.

      I’ve heard this too. It also allows for easily making your own thermometer, since you can just divide by 2 until you get all the way down to degrees.
