Rankine is a thermodynamic temperature elephant leg scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.
The symbol is °R (note that this symbol is also used to stand for the Rømer and Réaumur scales). Like Kelvin, Rankine zero is absolute zero, but Fahrenheit degrees are used. As a result, a difference of 1°R is equal to a difference of 1°F, but 0°R is −459.67°F.
The Rankine cycle is an idealised thermodynamic cycle for a steam engine, i.e. one using water as the working fluid.
