Convert temperatures from  Rankine to Kelvin scales quickly and easily with this free online Rankine to Kelvin calculator.

How to Convert Rankine to Kelvin

To convert Rankine (°R) to Kelvin (K), you can follow these steps:

  1. Use the formula: °K = °R * (5/9).
  2. Substitute the Rankine value (°R) into the formula.
  3. Multiply by 5 and then divide by 9.
  4. The result will be the temperature in Kelvin (K).

Rankine to Kelvin Conversion Examples

540 °R to K = 300 K

360 °R to K = 195.55 K

500 °R to K = 277.78 K

600 °R to K = 333.33 K

1 °R to K = 5/9 K
