Never heard about °R and °RA before this meme
It's the Rankine. Some Scottish dude wanted to use Kelvin without using Kelvin. It's basically the Fahrenheit scale but with 0˚R set at absolute zero.
0˚R = 0Kand1˚R = 0K + 1˚FFrom what I can gather, R and Ra are the same thing?
They are. The post could swap one of them out for Re or Rø instead and it would work, though

so, they meant °r probably

I had to look out up too!
Now look into °De. It's upside down!

Why would you do this to me?
