1 Kelvin equals
Rankine
1 K = 1.8 °R
The formula
Kelvin and Rankine do not share a zero point, so the conversion needs an offset as well as a scale factor.
°R = (K × 1 − 273.15 + 273.15) ÷ 0.55555556

Questions people ask
- What is 1 K in Rankine?
- 1 K is 1.8 °R. The two scales have different zero points, so the gap between them is not a fixed ratio.
- How do I convert Kelvin to Rankine by hand?
- These scales have different zero points, so you cannot use a single multiplier. Apply °R = (K × 1 − 273.15 + 273.15) ÷ 0.55555556.
- What is 1 Kelvin in Rankine?
- 1 Kelvin is 1.8 Rankine.
