    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

      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.

      Good thing °R and °RA aren’t pointing guns at each other

      Neither are °F and °R nor °K and °C

      This is almost artfully done

        This screenshot is a little bit hard to see, but from what I can tell:

        °RA is pointing at °R and °C
        °C is pointing at K and °F
        K is pointing at °R and at °F
        °R is pointing at °F (and the other gun isn’t aimed at anyone in particular)
        °F is pointing at K and at °C

        Emphasis disproves your claims, sadly. Perhaps there was another way to label them to make it fit, but that’s not what was done here.
