What do Rankine units measure?

Also, because temperature squared is related to energy using absolute scales gives a real indication of energy. Examiners will try to confuse students: Rankine Temp^2 is different from Fahrenheit Temp^2. When squared the base is important, (the base is negated in linear subtraction)

Rankine and Kelvin use the same unit sizes as Fahrenheit and Centigrade , respectively. But their zero is absolute zero. So if you have to talk about the freezing point of Helium or the ambient temperature of deep space, for example, it is easier. Nobody is going to say " the weather is cold today 260 Kelvin" Also, Rankine, Kelvin are absolute measures, it is wrong to use "degree" after them.

Player #33161631, Good point. Since each Rankine degree is the same size as Fahrenheit the freezing point of water is 491.7 degrees Rankine and the boiling point is 671.7 degrees Rankine (as in Fahrenheit 180 degee difference between freezing and boiling point of water). I'm not sure how much more useful it is than Kelvin, which is also an absolute scale.

Shame the answer doesn't say what the Rankine scale gives for freezing point or boiling point of water. If it is so useful, how come we dont all use it?
