Convert Fahrenheit to Celsius quickly for weather, cooking, lab work, and international temperature comparisons.
To convert Fahrenheit to Celsius, subtract 32 and multiply the result by 5/9. For example, 68°F equals 20°C.
Conversion Formula
Temperature conversion matters whenever you switch between US customary usage and metric-based countries. Weather forecasts, recipes, and scientific references often use different temperature scales.
This calculator is bidirectional, so it handles both Fahrenheit to Celsius and Celsius to Fahrenheit without extra steps.
| Fahrenheit (°F) | Celsius (°C) |
|---|---|
| 32 °F | 0 °C |
| 68 °F | 20 °C |
| 98.6 °F | 37 °C |
| 212 °F | 100 °C |
To convert fahrenheit to celsius, multiply the fahrenheit value by 0.5555555555555556. To convert in the opposite direction, divide by the same number (or multiply by 1.8). The relationship is exact and linear, so the same factor works for any value.
Use this quick-reference chart for the most common fahrenheit-to-celsius values. Each result is calculated with the exact 0.5555555555555556 factor.
| Fahrenheit (°F) | Celsius (°C) |
|---|---|
| 1 °F | 0.56 °C |
| 2 °F | 1.11 °C |
| 3 °F | 1.67 °C |
| 5 °F | 2.78 °C |
| 10 °F | 5.56 °C |
| 25 °F | 13.89 °C |

Subtract 32 from the Fahrenheit value, then multiply by 5/9 to get Celsius.
32°F equals 0°C, which is the freezing point of water.
Fahrenheit is still commonly used in the United States for weather, cooking, and home thermostats.
