Rankine to Celsius formula
°C = (°R*5/9)-273.15Temperature scales differ in both their zero point and their degree size, so a conversion needs a multiplication and an offset — unlike length or weight, where a single factor is enough.

About Rankine
The Rankine scale starts at absolute zero but uses Fahrenheit-sized degrees, and appears in US thermodynamics.
About Celsius
The Celsius scale puts the freezing point of water at 0° and its boiling point at 100° at standard pressure.
Frequently asked questions
What is 0°R in Celsius?
0°R equals -273.15°C.
What is normal body temperature?
37°C — about 37°C.
At what temperature do the two scales meet?
Only Celsius and Fahrenheit cross, at −40°. Kelvin and Rankine both start at absolute zero and never go negative.
