-40F 🤝 -40C

Pedantry:

K and °R agree on 0
K and °C agree on the unit difference
°F and °R agree on the unit difference
°R and °Ra are the exact same thing (??)

Imagine if some distance measuring system decided their zero was at like 10 feet.

Rankine and Kelvin have zero at the same point, which is absolute zero, and should not be used with the degree symbol

This concludes my TED talk

I went down a huge rabbit hole cause of this. I personally like °F over °C but agree it's arbitrary. So I tried to make a scale that started at the coldest air temp on earth (some day in Antarctica) and went to the hottest day on earth (some day in death valley) and put the coldest day at 0°A and the hottest at 100°A.

Sadly this made a scale that was less precise than I'd like. I like that I can feel the difference between 73°F and 74°F and don't want to have to use decimals.

So maybe the end points could be only places where people actually live. Well it looks like some people live in Russia around -70°C and some people live in northern Africa around 50°C so if you just take °C and add 60 you can get a -10 to 110 scale where most temps would fall between 0 and 100. Still has the unit difference of °C (which I don't like) but I like that most temps are between 0 and 100. I also don't really like negative temperature since it seems wonky.

To "fix" the unit scale you could just multiply everything by 2 so the difference between each full degree is half as much. So temps would be between -20 and 220. °A = 2(°C + 60) °A = 2(°C) + 120

And it turns out I (basically) created the Fahrenheit scale but moved. °F= 1.8(°C) + 32

TL;DR: I'm stupid and this was fun but also a waste of time lol

Never heard about °R and °RA before this meme

Comparing arbitrary degrees to absolutes. Notice K is the only one without the degree symbol...

Celsius tried to fit too much into 100 notches to please big math.

F is more nuanced with more notches, but the ends aren't logical. It coukd be shifted perhaps, but how?

If freezing was moved to 0, then water boiling would be 180

Perhaps C could have had a 200 degree range, then it would be closer to F and not so hard to convert.

But also: Scientists are important and we shouldn't make it too easy, it demeans their work. Maybe make the C scale show water boiling at 183.4521 degrees so scientific calculations are more impressive-looking and respectable.

When having a beer, I've always found it funny that one of the few imperial measurements metric nations kept around, the pint, America went and invented their own. Uncharacteristically a smaller version too.

This is more like if you measured altitude by counting from sea level vs the center of the earth vs the top of Mount Everest or something

0 lbs/lg = Absense of weight.

0 inches/centimeters = Absence of size.

0 Kelvin = Absence of heat.

If something is 0lbs, 0 inches and 0 Kelvin: does it even exist? 🤔

But R and K agree on zero

Meanwhile, Pi and the Fine Structure Constant watching the show, passing each other the popcorn.
