Kelvin to Rankine formula
°R = (K)*9/5Temperature 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 Kelvin
The kelvin is the SI base unit of temperature, starting at absolute zero; it uses the same degree size as Celsius.
About Rankine
The Rankine scale starts at absolute zero but uses Fahrenheit-sized degrees, and appears in US thermodynamics.
Frequently asked questions
What is 0K in Rankine?
0K equals 0°R.
What is normal body temperature?
37°C — about 558.27°R.
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.
