Convert Rankine to Fahrenheit
To convert degrees Rankine to degrees Fahrenheit, use °F = °R × 1 − 459.67: 527.67 °R = 68 °F, and 0 °R = -459.67 °F.
1 °R = -458.67 °F

How to Convert Rankine to Fahrenheit
- 1 °R = -458.67 °F
- 1 °F = 460.67 °R
- Example: convert 527.67 °R to °F: 527.67 °R = (527.67 × 1 − 459.67) °F = 68 °F
Formula
°F = °R × 1 − 459.67
Derivation from SI units:
- T(K) = T(°R) × 5/9; T(°R) = t(°F) + 459.67
- T(K) = (t(°F) + 459.67) × 5/9; t(°F) = t(°C) × 9/5 + 32
- Solving for °F: °F = °R × 1 − 459.67
Both units are defined exactly, so the factor is exact. Rankine definition: degree Rankine; Fahrenheit definition: degree Fahrenheit.
Worked examples
- 527.67 °R is 68 °F, the standard-air temperature.
527.67 × 1 − 459.67 = 68 °F - A gas at 1000 °R is at 540.33 °F.
1000 × 1 − 459.67 = 540.33 °F

Frequently asked questions
What is 0 °R in Fahrenheit?
0 °R is absolute zero, -459.67 °F.
What is the formula for degrees Rankine to degrees Fahrenheit?
°F = °R × 1 − 459.67. For example, 527.67 °R = 68 °F.
What is 0 °R in °F?
0 °R = -459.67 °F, and 100 °R = -359.67 °F.
How do I convert a temperature difference from °R to °F?
For a difference (an interval), ignore the offset and multiply by 1 only: a change of 10 °R is a change of 10 °F.
