How the Oven Temperature Converter works

Enter the temperature from your recipe in °C, °F or as a gas mark. The converter gives the conventional oven temperature in both scales, the nearest gas mark and the fan (convection) oven setting, which is usually about 20 °C lower. If the recipe is written for a fan oven, tick the box and it works the other way.

Formulas

Fahrenheit

°F = °C × 9 ÷ 5 + 32

Fan oven

fan °C ≈ conventional °C − 20

Examples

180 °C

= 356 °F, gas mark 4 (the chart rounds to 350 °F), or 160 °C in a fan oven.

Gas mark 6

= 200 °C or 400 °F — a hot oven for roasting.

Frequently asked questions

Why do fan ovens need a lower temperature?

The fan moves hot air over the food, so it cooks faster at the same setting.

Why doesn't 180 °C equal exactly 350 °F?

Recipes round to convenient numbers; 350 °F is 177 °C. A few degrees rarely matter.

Is my oven accurate?

Many ovens run hot or cold by 10–20 °C. An oven thermometer shows the real temperature.
