Convert Kelvin to degrees Rankine
1 kelvin = 1.8 degrees Rankine · °R = K × 9/5
When you need this conversion
This conversion goes from kelvin, the SI absolute temperature scale starting at absolute zero, to degrees Rankine, the absolute scale built on Fahrenheit degrees used in US engineering. 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
°R = K × 9/5Temperature scales do not share a common zero point, so converting kelvin to degrees Rankine requires both a scaling step and an offset rather than a single multiplication.
