Oven dials use Celsius, Fahrenheit or gas marks depending on the country and appliance. This converter shows all three, plus a fan-oven adjustment, so a recipe can be followed without guessing.
The Formula
°F = °C × 9/5 + 32; gas mark ≈ (°C − 121) ÷ 14Frequently Asked Questions
What is 180 °C in a fan oven?
About 160 °C fan, or 320 °F. Fan ovens circulate heat more efficiently, so recipes usually reduce the temperature by 20 °C.
Is gas mark 4 the same as 180 °C?
Gas mark 4 is conventionally about 180 °C / 350 °F, though appliance calibration varies.
