Convert Degrees Rankine to kelvin
1 degree Rankine = 0.555556 kelvin · K = °R × 5/9
When you need this conversion
This conversion goes from degrees Rankine, the absolute scale built on Fahrenheit degrees used in US engineering, to kelvin, the SI absolute temperature scale starting at absolute zero. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.

The formula
K = °R × 5/9Temperature scales do not share a common zero point, so converting degrees Rankine to kelvin requires both a scaling step and an offset rather than a single multiplication.
