About converting Rankine to Celsius
Degrees Rankine are an absolute-temperature scale with Fahrenheit-sized intervals and are used in some engineering contexts. 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. Degrees Celsius use the freezing and boiling behavior of water as familiar reference points and are standard in most countries. Rankine and Celsius use different reference points and interval sizes, so their relationship is calculated with the temperature-scale formula shown above.
Rankine and Celsius conversion
Temperature scales use different zero points and intervals, so the calculator applies the appropriate temperature formula rather than a single multiplication factor.
Worked Rankine to Celsius examples
These examples use the appropriate temperature-scale relationship: 0 °R = -273.15 °C; 20 °R = -262.0388888889 °C; 100 °R = -217.5944444444 °C.
