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 = 0K and 1˚R = 0K + 1˚F

From 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

I just learned about °Ré and °Rø and now my head hurts.

Now look into °De. It's upside down!
