Celsius, fan, Fahrenheit and gas mark, sorted
British recipes and ovens are a mix of scales, and getting them wrong is the difference between a risen cake and a flat one. Enter a conventional Celsius temperature and this converter gives the fan (convection) equivalent, the Fahrenheit value and the gas mark. The key rule most people miss: a fan oven runs about 20°C hotter than a conventional one at the same setting, so you drop the temperature by 20 when a recipe was written for a conventional oven.
Gas marks do not map perfectly onto exact degrees, so the chart shows the nearest standard setting used in UK cookbooks. For getting a recipe into an air fryer, use the air fryer conversion calculator.
Frequently asked questions
Is the oven temperature converter converter free?
Yes. It is completely free, with no sign-up and nothing to install. It runs entirely in your browser.
Are these figures exact?
They are reliable guides based on standard UK values, but ingredients, ovens and appliances vary. For anything involving meat, always check it is cooked through with a thermometer rather than relying on time alone.
