About converting Kelvin to Rankine
Degrees Rankine are an absolute-temperature scale with Fahrenheit-sized intervals and are used in some engineering contexts. Kelvin and Rankine use different reference points and interval sizes, so their relationship is calculated with the temperature-scale formula shown above. Kelvin is the SI base unit of thermodynamic temperature and begins at absolute zero, which makes it central to scientific work. This conversion involves units that are temperature scales with different reference points and interval sizes. Unlike a simple length conversion, changing between these scales requires an offset as well as a scale adjustment.
Kelvin and Rankine conversion
Temperature scales use different zero points and intervals, so the calculator applies the appropriate temperature formula rather than a single multiplication factor.
Worked Kelvin to Rankine examples
These examples use the appropriate temperature-scale relationship: 0 K = 0 °R; 20 K = 36 °R; 100 K = 180 °R.
