Rankine

(Redirected from Rankine scale)

Rankine is a now rarely used temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

The symbol is usually given as °R, but since this may lead to confusion with the Rømer or Réaumur scales, °Ra is to be preferred. Like kelvin, Rankine zero is absolute zero, but Fahrenheit degrees are used. As a result, a difference of 1 °Ra is equal to a difference of 1 °F, but 0 °Ra is −459.67 °F.

The Rankine cycle is an idealised Thermodynamic cycle for a steam engine - ie one using water as the working fluid.
