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 (??)Celsius and Fahrenheit agree on -40, but since they're scales that scale at different rates there's bound to be some value where they intersect rather than some meaningful number like Kelvin and Rankine being zeroed to Absolute Zero
Same with 574.59°F = 574.59K
Two lines which are not perpendicular will meet at one point?
Also Rankine, being an absolute scale, theoretically shouldn't be in ° anything, and it's only some weird historical quirk that is the reason it usually is called degrees.
I am not sure I follow that. The scale is always relative right? It’s just the zero that’s absolute. But that’s also the case with measuring angles where we do use the degree symbol.
It’s just the zero that’s absolute
Right, that's what makes Rankine and Kelvin absolute scales, while Fahrenheit and Celsius are relative.

I think °R is supposed to be Réaumur
