Rankine (°R)
The Rankine scale is an absolute Fahrenheit-scale system: 0°R is absolute zero and one Rankine degree equals one Fahrenheit degree.
Rankine is used in some US engineering fields, especially thermodynamics and aerospace calculations.

Selected °R values converted to °F using the exact offset formulas from this tool.
| °R | °F |
|---|---|
| 491.67 | 32 |
| 539.67 | 80 |
| 580 | 120.33 |
| 671.67 | 212 |
Exact offset formulas in both directions, plus a worked example.
°F = °R − 459.67
°R = °F + 459.67
Subtract 459.67 from Rankine to get Fahrenheit.
Add 459.67 to Fahrenheit to get Rankine.
Example: convert 540 °R to °F
540 °R → 80.33 °F (rankine to fahrenheit)
Short background on the units used in this conversion.
The Rankine scale is an absolute Fahrenheit-scale system: 0°R is absolute zero and one Rankine degree equals one Fahrenheit degree.
Rankine is used in some US engineering fields, especially thermodynamics and aerospace calculations.
The Fahrenheit scale places the freezing point of water at 32° and the boiling point at 212° at standard pressure.
Fahrenheit is used for weather, cooking, and indoor thermostat settings in the United States and a few other regions.
