Oven Temperature Conversion

To convert oven Celsius to Fahrenheit, multiply by 1.8 and add 32 — then round to the nearest 25 °F your dial actually has: 180 °C is exactly 356 °F, so set 350 °F. Fan ovens run about 20 °C hotter in effect, so reduce fan settings by 20 °C.

180 °C = 356 °F

Fan / convection oven: about 160 °C. Nearest gas mark: 4 (moderate).
