Kelvin (K) to Rankine (°R) Conversion

Kelvin

The Kelvin is the SI base unit of thermodynamic temperature, named after Lord Kelvin who proposed an absolute temperature scale in 1848. Zero Kelvin (0 K), absolute zero, represents the theoretical lowest possible temperature (−273.15 °C). No degree symbol is used because Kelvin is an absolute scale, not a degree-based one. The Kelvin is universally used in physics and chemistry because it is directly proportional to thermal energy.

Rankine

The Rankine scale is an absolute temperature scale using the same degree size as Fahrenheit but with zero at absolute zero (−459.67 °F). It is to Fahrenheit what Kelvin is to Celsius. Used primarily in US aerospace engineering and thermodynamic cycle analysis where Fahrenheit-sized degrees are conventional but absolute temperature values are required. Water freezes at 491.67 °R and boils at 671.67 °R.
