A recipe says “bake at 350 °F”, but your oven is in Celsius — or it is a fan oven, or it uses gas marks. This chart converts all of them so your cakes come out right.

Celsius values are rounded the way recipes usually print them.
Fan ovens: reduce by about 20 °C
Fan (convection) ovens circulate hot air, so they cook faster. As a rule, lower the conventional temperature by about 20 °C (25 °F) or shorten the cooking time.
The conversion formula
°C = (°F − 32) × 5/9. Example: (350 − 32) × 5/9 = 176.7 °C, which recipes round to 180 °C.

About gas mark 6.
Do I need to adjust for an air fryer?
Air fryers behave like small fan ovens; reduce the temperature by about 20 °C and check early.
