Quick answer
180 °C is 350 °F, gas mark 4 – or 160 °C in a fan oven. 200 °C is 400 °F, gas mark 6 (180 °C fan).
Recipes from the US give oven temperatures in Fahrenheit, British recipes often in gas marks, and European ones in Celsius – sometimes for a fan oven, sometimes not. A fan (convection) oven cooks hotter, so set it about 20 °C lower than a conventional oven.
Find the temperature from your recipe in any column and read across.

Fahrenheit values are rounded to the nearest 5 °F, as on oven dials. Oven thermostats vary: an oven thermometer shows the real temperature.
Tips for converting oven temperatures
- Check whether the recipe was written for a fan (convection) or conventional oven.
- For a fan oven, use the fan column – about 20 °C (25 °F) lower.
- Gas mark 4 (180 °C / 350 °F) is the most common baking temperature for cakes and cookies.
- Check a little before the end of the baking time the first time you convert a recipe.
