degree Rankine (°R)
Rankine is an absolute temperature scale with 1 °R = 5/9 K; 0 °R is absolute zero.

Frequently asked questions
How many kelvins are in 1 degree Rankine?
1 °R ≈ 0.5556 K. K = ((°R × (5 / 9)) + (0) × (1)) + (0)
How do I convert °R to K?
K = ((°R × (5 / 9)) + (0) × (1)) + (0)
Why does this conversion need more than multiplication?
Temperature scales have different zero points. Apply the scale and offset in the formula; below absolute zero is a mathematical result only.
