How to convert Kelvin to Rankine
Kelvin and Rankine are related by a formula rather than a single factor. Temperature conversions are needed for weather, cooking, science and travel. Temperature scales have different zero points, so conversions use offsets as well as ratios.

About the units
Kelvin (K)
Kelvin is the SI temperature scale starting at absolute zero; 0 K = −273.15 °C.
Rankine (°R)
Rankine is an absolute scale with Fahrenheit-sized degrees; 0 °R is absolute zero.
How to use this converter

- The result in Rankine appears instantly — no button needed.
- See the same value in every other temperature unit just below.
- Use “Swap units” to convert Rankine back to Kelvin.
When you’ll use the kelvin to rankine conversion
Converting kelvin to rankine comes up more often than you might expect — for example when setting an oven or thermostat, reading a weather forecast while traveling, or baking with a recipe from another country. Type your number once and you get the exact answer plus every related unit, so you don’t need to convert twice.
Watch out for these mix-ups
- Temperature scales have different zero points, so you cannot just multiply.
- A change of 1 °C equals a change of 1.8 °F — but 1 °C is not 1.8 °F.
Tips for better results
- Double-check which system a unit belongs to (for example US vs UK gallons).
- Use the swap button to convert in the opposite direction instantly.
- Bookmark the conversions you use most — each pair has its own page.
Frequently asked questions
How many Rankine are in one kelvin?
1.8 °R corresponds to 1 K. Because this scale uses an offset or an inverse relationship, there is no single multiplication factor — use the formula above.
How do I convert Kelvin to Rankine?
Apply the formula shown on this page, or enter your value in the converter for an instant exact answer.
What is 37 K in °R?
37 K = 66.6 °R. Also, 0 K = 0 °R and 100 K = 180 °R.
What is the difference between a kelvin and a rankine?
Kelvin is the SI temperature scale starting at absolute zero; 0 K = −273.15 °C. Rankine is an absolute scale with Fahrenheit-sized degrees; 0 °R is absolute zero.
