Conversion factor

°R = K × 1.8

1 K = 1.8 °R

Multiply by 1.8 °R to go from Kelvin to degrees Rankine, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.

Frequently asked questions

How many degrees Rankine are in one Kelvin?

One Kelvin is 1.8 °R, so 100 K is 180 °R.

What is the formula to convert Kelvin to degrees Rankine?

°R = K × 1.8. Multiply the value in Kelvin by 1.8 to get degrees Rankine.

How do I convert degrees Rankine back to Kelvin?

K = °R × 0.555555556, so 1 °R is 0.555555556 K. The °R to K page carries the same table in that direction.
