Use this page to convert rankine values into kelvin, with background details, formulas, a worked example, and a quick conversion table.

This conversion uses an offset formula rather than a single multiplier because the temperature scales start from different zero points.

deg R to K: Apply the scale formula and then add or remove the required offset.

Example: 25 deg R = 13.8888888888889 K

Rankine starts at absolute zero, and one Rankine degree is the same interval as one Fahrenheit degree.

History: The Rankine scale was developed for thermodynamic calculations in systems based on Fahrenheit.

Current use: Rankine appears in some engineering, thermodynamics, and legacy US customary calculations.

Also written as deg R.

Kelvin uses the same interval size as Celsius, with absolute zero at 0 K.

History: It was developed for thermodynamics and later integrated into the SI system.

Current use: Kelvin is used in science, engineering, and color temperature references.

Also written as K, kelvins.
