Rankine (°R) to Celsius (°C) Conversion

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.

Celsius

The Celsius scale sets 0 °C at the freezing point of water and 100 °C at its boiling point at standard atmospheric pressure. Proposed by Anders Celsius in 1742, it became the international standard for scientific and everyday temperature measurement in all countries that have adopted SI. The Celsius degree is identical in magnitude to the Kelvin, so temperature differences in Celsius and Kelvin are numerically equivalent, though their zeros differ by exactly 273.15.
