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 °C using the exact offset formulas from this tool.
| °F | °C |
|---|---|
| -40 | -40 |
| 0 | -17.7777777778 |
| 32 | 0 |
| 68 | 20 |
| 98.6 | 37 |
| 212 | 100 |
Exact offset formulas in both directions, plus a worked example.
°C = (°F − 32) × 5/9
°F = °C × 9/5 + 32
Subtract 32 from Fahrenheit, then multiply by 5/9 to get Celsius.
Multiply Celsius by 9/5, then add 32 to get Fahrenheit.
Example: convert 98.6 °F to °C
98.6 °F → 37 °C (fahrenheit to celsius)
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 Celsius scale sets the freezing point of water at 0° and the boiling point at 100° at standard atmospheric pressure.
Celsius is the everyday temperature scale in most countries, on weather forecasts, and in science alongside kelvin.
