Use this page to convert kelvin values into rankine, 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.

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

Example: 25 K = 45 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.

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.
