Degrees Celsius to degrees Fahrenheit
1 degree Celsius = 33.8 degrees Fahrenheit
Type a value in degrees Celsius (°C) to get degrees Fahrenheit (°F) straight away. Both units belong to temperature, measured here against the kelvin.
1 °C = 33.8 °F
Formula
°F = °C × 9/5 + 32
Multiply by 9/5 (1.8) because a Fahrenheit degree is smaller, then add 32 because water freezes at 32 °F. Here °C is the value in degrees Celsius and °F is the result in degrees Fahrenheit.
Worked example: 37 degrees Celsius: put 37 into °F = °C × 9/5 + 32. The result is 98.6 degrees Fahrenheit.

Everyday degrees Celsius in degrees Fahrenheit
| What it is | °C | °F |
|---|---|---|
| a home freezer | -18 °C | -0.4 °F |
| a fridge | 4 °C | 39.2 °F |
| room temperature | 20 °C | 68 °F |
| body temperature | 37 °C | 98.6 °F |
| a moderate oven | 180 °C | 356 °F |
Quick estimate in your head
Double the °C and add 30. At 20 °C that gives 70 °F against an exact 68 °F; the error grows away from 10 °C.
Watch out for
- Do not add 32 when converting a temperature difference; use only the 9/5 factor.
- For a temperature change (not a reading), use only the 1.8 factor: a rise of 10 °C is a rise of 18 °F, not 50 °F.
About the units
Degree Celsius (°C). Water freezes at 0 °C and boils at 100 °C at sea level. Used for weather almost everywhere.
Degree Fahrenheit (°F). Water freezes at 32 °F and boils at 212 °F. Used for weather and cooking in the US.
Going the other way, 1 degree Fahrenheit is -17.2222 degrees Celsius.
