OK, I'm not a physicist.

And the reason its degrees K is because the kinetic energy in a gas is
proportional to its temperature in K. Just look up thermal efficiency
in Winky.

But I'm enough of one to know that while one kelvin is equivalent to one
degree celsius, it isn't a degree. It's just a kelvin.

Correct. You can have a difference of 10 degrees Centigrade, 10 degrees
Celcius or 10 Kelvin and they are the same ... you cannot have 10
degrees Kelvin, it is just wrong! °C is a relative scale, a gradient,
hence the degrees, whereas K is an absolute scale, a fundamental unit,
hence no degrees.

Now, how about Rankine?
