Rankine to Fahrenheit formula
°F = (°R*5/9)*9/5-459.67Temperature 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 Fahrenheit
The Fahrenheit scale puts water’s freezing point at 32° and its boiling point at 212°, and is used mainly in the United States.
Frequently asked questions
What is 0°R in Fahrenheit?
0°R equals -459.67°F.
What is normal body temperature?
37°C — about 98.6°F.
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.
