How to Convert Rankine to Celsius
The rankine and celsius are both units of temperature measurement. To convert rankine to celsius, use the formula °C = (°R - 491.67) × 5/9.
Formula
Step-by-Step Example
Convert 100 °R to celsius:
Formula: °C = (°R - 491.67) × 5/9
100 - 491.67 = -391.67
-391.67 × 5/9 = -217.59444444
100 °R = -217.59444444 °C

About These Units
Rankine (°R)
Rankine (°R) is an absolute temperature scale using Fahrenheit-sized degrees. Absolute zero is 0°R (-459.67°F). Water freezes at 491.67°R and boils at 671.67°R. Used in some US engineering applications, particularly thermodynamics. Named after Scottish engineer William Rankine.
Celsius (°C)
Celsius (°C), also called centigrade, is the metric temperature scale used by most countries worldwide. Water freezes at 0°C and boils at 100°C at standard pressure. To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. Normal body temperature is 37°C. Named after Swedish astronomer Anders Celsius.
