Rankine to Kelvin (°R to K)
Convert °R to K — Temperature converter
Also written as R to K.
Converting Rankine to Kelvin uses the formula K = °R × 5/9. Both are temperature scales that measure how hot or cold something is, so the change is a formula rather than a single multiplier. A few reference points: 0 °R = -5.684342e-14 K, 37 °R = 20.555556 K, and 100 °R = 55.555556 K.
