Usage

The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit.

The symbol for degrees Rankine is °R (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol.

Some temperatures relating the Rankine scale to other temperature scales are shown in the table below.
