How to convert an oven temperature
- Type the temperature from your recipe, or a gas mark such as 4 or 1/2.
- Choose what it’s in under From: °C, °C fan, °F or gas mark. Then choose what your oven uses under To.
- Read the setting for your oven. All four scales are listed, and the chart highlights the nearest standard setting.

Recipes use round numbers, so the °C and °F columns are close matches rather than exact conversions. For an exact conversion of any temperature, use the Celsius to Fahrenheit converter.
Getting the temperature right
An oven’s dial and its real temperature don’t always match, especially in older ovens. An oven thermometer on the middle shelf shows the real temperature, so you can adjust the dial to match. Fan ovens heat more evenly, which is why they need less heat; if your recipe already gives a fan temperature, don’t take the 20 degrees off twice. Making more or less than the recipe says? The recipe scaler resizes the ingredient list.
