Degrees Rankine to Kelvin converter

To convert degrees Rankine to kelvin, enter the value in the first field. The result in kelvin is calculated automatically using the exact conversion factor.

1 °R ≈ 0.555555555556 K
1 K = 1.8 °R

Formula: K = °R × 5/9
°R = K × 1.8

Definitions: 0 °R = 0 K; 1 °R step = 5/9 K

The degree Rankine (°R) is an absolute temperature scale with degrees the size of Fahrenheit degrees, so 0 °R is absolute zero. It is used mainly in some American engineering fields such as thermodynamics and aerospace.

The kelvin (K) is the SI base unit of thermodynamic temperature, and 0 K is absolute zero. It uses the same step size as a degree Celsius, is written without a degree sign, and is used in science, engineering and for the color temperature of lighting.
