How the Oven Temperature Converter works

Enter the temperature and its unit.

°F = °C × 9 ÷ 5 + 32.

Fan (convection) ovens cook faster, so many recipes lower the setting by about 20 °C (25 °F).

The formula

°F = °C × 9/5 + 32°C = (°F − 32) × 5/9

Worked example

Using the default values shown in the calculator:

Temperature180
Unit°C
  1. 180 °C × 9 ÷ 5 + 32 = 356 °F.
  2. In a fan oven use about 160 °C (320 °F).

Result:

Celsius180
Fahrenheit356
Fan oven (°C, about 20 °C lower)160
Fan oven (°F)320

Frequently asked questions

Is the fan adjustment exact?

No. It varies between ovens. Check food earlier than the recipe says and use an oven thermometer.

What is 350 °F in Celsius?

About 177 °C, usually rounded to 180 °C.
