The short answer
- °F = °C × 9/5 + 32
- 0 °C = 32 °F
- 100 °C = 212 °F
Worked example37 °C = 98.6 °F
To convert degrees Celsius to degrees Fahrenheit, use °F = °C × 9/5 + 32.
Degree celsius. The Celsius scale puts the freezing point of water at 0 °C and its boiling point at sea level at 100 °C. 0 °C is 273.15 K.
Degree fahrenheit. On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so a change of 1 °F is 5/9 of a degree Celsius.

Values are rounded to 7 significant figures.
Use °F = °C × 9/5 + 32. For example, 37 °C = 98.6 °F.
37 °C is 98.6 °F.
Yes. Both units have exact legal definitions, so the factor is exact. Values on this page are rounded to 7 significant figures.
