Convert Fahrenheit to Rankine
To convert degrees Fahrenheit to degrees Rankine, use °R = °F × 1 + 459.67: 68 °F = 527.67 °R, and 0 °F = 459.67 °R.
1 °F = 460.67 °R

How to Convert Fahrenheit to Rankine
- 1 °F = 460.67 °R
- 1 °R = -458.67 °F
- Example: convert 68 °F to °R: 68 °F = (68 × 1 + 459.67) °R = 527.67 °R
Formula
°R = °F × 1 + 459.67
Derivation from SI units:
- T(K) = (t(°F) + 459.67) × 5/9; t(°F) = t(°C) × 9/5 + 32
- T(K) = T(°R) × 5/9; T(°R) = t(°F) + 459.67
- Solving for °R: °R = °F × 1 + 459.67
Both units are defined exactly, so the factor is exact. Fahrenheit definition: degree Fahrenheit; Rankine definition: degree Rankine.
Worked examples
- Standard air at 68 °F is 527.67 °R.
68 × 1 + 459.67 = 527.67 °R - Exhaust gas at 300 °F is 759.67 °R absolute.
300 × 1 + 459.67 = 759.67 °R

Frequently asked questions
How do I convert °F to °R?
Add 459.67: 60 °F = 519.67 °R.
What is the formula for degrees Fahrenheit to degrees Rankine?
°R = °F × 1 + 459.67. For example, 68 °F = 527.67 °R.
What is 0 °F in °R?
0 °F = 459.67 °R, and 100 °F = 559.67 °R.
How do I convert a temperature difference from °F to °R?
For a difference (an interval), ignore the offset and multiply by 1 only: a change of 10 °F is a change of 10 °R.
