Celsius to Fahrenheit
Convert temperatures from °C to °F. Free, fast and easy to use.
How it works
Multiply the temperature in degrees Celsius by 9/5 and add 32. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F).
Formula
°F = °C × 9/5 + 32
Worked examples
- 37 °C = 98.6 °F
- 180 °C = 356 °F
- -10 °C = 14 °F
