How to convert kelvins to degrees Rankine
°R = K × 9/5Temperature scales have different zero points, so the conversion needs an offset as well as a scale factor. In one step: °R = K × 1.8 + 0.

About the units
Kelvin (K)
The SI base unit of thermodynamic temperature, defined by fixing the Boltzmann constant. 0 K is absolute zero; a kelvin is the same size as a Celsius degree.
Degree Rankine (°R)
An absolute scale with Fahrenheit-sized degrees: 0 °R is absolute zero and 491.67 °R is the freezing point of water. Used in some US thermodynamics work.
Frequently asked questions
What is the formula to convert kelvins to degrees Rankine?
°R = K × 9/5. Temperature scales have different zero points, so the conversion needs an offset as well as a scale factor. In one step: °R = K × 1.8 + 0.
What is 273.15 kelvins in degrees Rankine?
273.15 K = 491.67 °R.
What is 0 K in °R?
0 K = 0 °R.
Can I just multiply to convert kelvins to degrees Rankine?
Yes. Both scales start at absolute zero, so the conversion is a pure multiplication by 1.8.
Is this K to °R converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
