How to convert degrees Rankine to degrees Celsius
Use the formula °C = (°R − 491.67) × 5/9. Temperature scales have different zero points, so you cannot simply multiply by a single factor.
°C = (°R − 491.67) × 5/9
Example
To convert 500 degrees Rankine to degrees Celsius: apply the formula above = 4.627777778 °C.

About the units
Rankine (°R)
Rankine is an absolute scale using Fahrenheit-sized degrees; 0 °R is absolute zero. It appears in some US engineering work.
Celsius (°C)
On the Celsius scale water freezes at 0 °C and boils at 100 °C at sea level. It is used in most of the world.
