What is a Rankine?

Rankine is a unit used in temperature conversions and practical measurement work.

Rankine is a unit used in temperature conversions and practical measurement work.

The Rankine scale was proposed by Scottish engineer William Rankine in 1859. It is an absolute scale with Fahrenheit-sized degrees, so 0 °R is absolute zero; it is still used in some US engineering work.

Measurement system: SI, meteorological and customary temperature scales. SI equivalent: Reference relationship defined by the converter dataset.
