Rankine scale

The Rankine scale is a temperature scale as the Kelvin scale at absolute zero temperature has its zero value, but in contrast to these uses the distance scale of the Fahrenheit scale. It is named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859 ( see also the Rankine - Hugoniot equation). It is used mainly in English-speaking countries.

The distance of one degree Rankine ( unit symbol: ° Ra or restricted ° R ) is therefore equal to the difference of one degree Fahrenheit, but the absolute zero is 0 degrees Rankine or -459.67 degrees Fahrenheit. Degrees Rankine is not a SI unit.

Temperature differences with the scale distance between the Fahrenheit scale can also be specified in ° Ra, as their value does not change when differences:
