How to convert degrees Rankine to kelvins
K = °R × 5/9Temperature scales have different zero points, so the conversion needs an offset as well as a scale factor. In one step: K = °R × 0.5555555556 + 0.

About the units
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.
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.
Frequently asked questions
What is the formula to convert degrees Rankine to kelvins?
K = °R × 5/9. Temperature scales have different zero points, so the conversion needs an offset as well as a scale factor. In one step: K = °R × 0.5555555556 + 0.
What is 491.67 degrees Rankine in kelvins?
491.67 °R = 273.15 K.
What is 0 °R in K?
0 °R = 0 K.
Can I just multiply to convert degrees Rankine to kelvins?
Yes. Both scales start at absolute zero, so the conversion is a pure multiplication by 0.5555555556.
Is this °R to K 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.
