Celsius to Rankine Converter
How to convert Celsius to Rankine
°R = °C × 1.8 + 491.67
To convert Celsius to Rankine, multiply the value in Celsius by 1.8, then add 491.67.
1 °C = 493.47 °R
Examples
- Normal body temperature: 37 °C × 1.8 + 491.67 = 558.27 °R
- Water boils at sea level: 100 °C × 1.8 + 491.67 = 671.67 °R
Good to know
The scales differ in both zero point and degree size: °R = (°C + 273.15) × 1.8. Water freezes at 0 °C, which is 491.67 °R.
The Rankine scale starts at absolute zero, so there are no negative Rankine temperatures.

Unit definitions
- Celsius (°C)
- The Celsius scale is defined as the temperature in kelvins minus 273.15, which puts the freezing point of water at about 0 °C and its boiling point at about 100 °C at sea-level pressure. It is the everyday temperature scale in most of the world.
- Rankine (°R)
- The Rankine scale starts at absolute zero and uses degrees the same size as the degree Fahrenheit, so a temperature in degrees Rankine is the Fahrenheit temperature plus 459.67. It is used in some US engineering calculations.
