72.2 °R ≈ 40.1111 K. To convert Degrees Rankine to Degrees Kelvin, multiply by 0.555556: 72.2 × 5/9 = 40.1111.
How to convert Degrees Rankine to Degrees Kelvin
K = °R × 5/9
- 1 °R = 0.555556 K (and 1 K = 1.7999986 °R).
- Multiply the amount by the factor: 72.2 × 5/9 = 40.1111.
- Answer: 72.2 °R ≈ 40.1111 K (rounded to 6 significant figures).

Good to know
°F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9. K = °C + 273.15.
Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level.
