About the degree Rankine
Fahrenheit scale starting at absolute zero. Used in US engineering.
About the kelvin
Absolute temperature scale. Same size as Celsius, 0 K = absolute zero.
How degree Rankine to kelvin conversion works
Temperature scales are affine: the result needs both a scale factor and a zero-point offset. That is why °R to K cannot be reduced to a simple percentage change.
The right unit depends on the convention used by your industry, country, instrument, or source document.

Frequently asked questions
Frequently Asked Questions
How do I convert degree Rankine to kelvin?
Multiply the degree Rankine value by 0.555556 to get it in kelvin. For example, 10 °R = 5.5556 K.
What is 1 °R in K?
1 °R = 0.555556 K.
What is 100 °R in K?
100 °R = 55.5556 K.
What is the formula?
Temperature is an affine quantity. The formula depends on the source and target scales; °R → K uses: T(K) = T(°R) × 0.555556 + 0, then applies the inverse on the other side.
