How to convert rankine to kelvin

The conversion from Rankine to Kelvin uses the formula below. Unlike length or weight, temperature scales don’t share a zero point, so you can’t just multiply.

Formula
K = °R × 5/9

For example:

  • →5 °R = 2.77778 K
  • →100 °R = 55.5556 K

Quick reference

  • ▸1 °R = 0.555556 K
  • ▸1 K = 1.8 °R
