Convert Kelvin to Degrees Rankine (K to °R)
1 K = 1.8 °R. Convert Kelvin to degrees Rankine with the exact factor, a common-values table and a free converter.
Conversion factor
°R = K × 1.8
1 K = 1.8 °R
Multiply by 1.8 °R to go from Kelvin to degrees Rankine, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.
K to °R table
| Kelvin (K) | Degrees Rankine (°R) |
|---|---|
| 1 K | 1.8 °R |
| 2 K | 3.6 °R |
| 5 K | 9 °R |
| 10 K | 18 °R |
| 20 K | 36 °R |
| 50 K | 90 °R |
| 100 K | 180 °R |
Every figure is computed at build time by the site’s own converter from the temperature unit registry. For a value that is not listed, put it into the interactive converter.
Frequently asked questions
How many degrees Rankine are in one Kelvin?
One Kelvin is 1.8 °R, so 100 K is 180 °R.
What is the formula to convert Kelvin to degrees Rankine?
°R = K × 1.8. Multiply the value in Kelvin by 1.8 to get degrees Rankine.
How do I convert degrees Rankine back to Kelvin?
K = °R × 0.555555556, so 1 °R is 0.555555556 K. The °R to K page carries the same table in that direction.
