## Rankine To Celsius Formula

Use this formula to convert a temperature in Rankine (K) to Celsius (°R).

Celsius (°C) = (Rankine - 491.67) / 1.8

If required, there are worked examples below which use this formula to show how to convert a temperature in Rankine to a temperature in Celsius.

As with any math calculation and conversion, it's good practice to double check your results. If you are using this formula for your own conversions, you can check your result with the Rankine to Celsius calculator.

Temperature scales are usually named after the person who created them. The temperature scales used in this formula were created by William John Macquorn Rankine (1820-1872), and Anders Celsius (1701–1744).

Given the Rankine scale was invented many years after the Celsius scale, it's probable William Rankine also created this formula for converting Rankine to Celsius.
