Fahrenheit (°F)
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.

Selected °F values converted to °R using the exact offset formulas from this tool.
| °F | °R |
|---|---|
| -40 | 419.67 |
| 0 | 459.67 |
| 32 | 491.67 |
| 68 | 527.67 |
| 98.6 | 558.27 |
| 212 | 671.67 |
Exact offset formulas in both directions, plus a worked example.
°R = °F + 459.67
°F = °R − 459.67
Add 459.67 to Fahrenheit to get Rankine.
Subtract 459.67 from Rankine to get Fahrenheit.
Example: convert 98.6 °F to °R
98.6 °F → 558.27 °R (fahrenheit to rankine)
Short background on the units used in this conversion.
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.
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.
°R = °F + 459.67.Jump to any temperature conversion starting from fahrenheit — including the reverse direction and every other unit in our dataset.
