How to convert Celsius to Rankine

To convert Celsius to Rankine, add 273.15 then multiply by 9/5. Formula: °R = (°C + 273.15) × 1.8. For example, 100°C = (100 + 273.15) × 1.8 = 671.67°R.

Going the other way — to convert Rankine to Celsius — divide by 1.8 then subtract 273.15. So 671.67°R ÷ 1.8 − 273.15 = 100°C.

Rankine is an absolute temperature scale like Kelvin but uses Fahrenheit-sized degrees. 0°R = absolute zero = −273.15°C = −459.67°F. Rankine is used in some engineering applications in the US.

Frequently asked questions

What is the Rankine scale?
Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees. 0°R = absolute zero. It is used in some US engineering and thermodynamics applications.
What is 0°C in Rankine?
0°C = 491.67°R. This is the freezing point of water on the Rankine scale.
What is 100°C in Rankine?
100°C = 671.67°R. This is the boiling point of water on the Rankine scale.
What is the difference between Rankine and Kelvin?
Both start at absolute zero but use different degree sizes. Kelvin uses Celsius-sized degrees while Rankine uses Fahrenheit-sized degrees. 1 K = 1.8°R.
How do you convert Rankine to Fahrenheit?
To convert Rankine to Fahrenheit, subtract 459.67. So 671.67°R − 459.67 = 212°F (boiling point of water).
