How to Convert Rankine to Kelvin
The rankine and kelvin are both units of temperature measurement. To convert rankine to kelvin, use the formula K = °R × 5/9.
Formula
Step-by-Step Example
Convert 100 °R to kelvin:
Formula: K = °R × 5/9
100 × 5/9 = 55.555555556
100 °R = 55.555555556 K

About These Units
Rankine (°R)
Rankine (°R) is an absolute temperature scale using Fahrenheit-sized degrees. Absolute zero is 0°R (-459.67°F). Water freezes at 491.67°R and boils at 671.67°R. Used in some US engineering applications, particularly thermodynamics. Named after Scottish engineer William Rankine.
Kelvin (K)
Kelvin (K) is the SI base unit for temperature, used in science and engineering. Absolute zero (0 K) is -273.15°C or -459.67°F—the coldest possible temperature where molecular motion stops. No degree symbol is used with Kelvin. Water freezes at 273.15 K. Named after Lord Kelvin.
