How to convert Rankine to Celsius

Conversion factor and calculation steps from Rankine (°R) to Celsius (°C).

Conversion logic

Temperature is converted through the Celsius scale: first the zero offset, then the size of the degree.

°R = (°C + 273.15) × 9/5

1 °R × 5/9 − 273.15 = -272.594444444 °C
