Oven Temperature Converter

Convert recipe oven temperatures between °C, °F and UK gas marks. The converter also shows the usual US dial setting and the lower temperature for a fan (convection) oven.

How to use the Oven Temperature Converter

Enter the oven temperature from your recipe.
Choose whether it is °C, °F or a gas mark.
Read the equivalent settings — including the fan-oven temperature.

How it works

Celsius and Fahrenheit are converted exactly (°F = °C × 9/5 + 32), then rounded to the nearest 25 °F, the way US oven dials and recipes are marked. Gas marks follow the standard UK equivalents. For a fan or convection oven, reduce the temperature by about 20 °C (25 °F) or shorten the cooking time.
