Oven Temperature FAQ
Common questions about oven conversion and fan settings.
How much lower is a fan oven?
A common starting point is about 20 C lower than a conventional oven. Actual ovens vary, so watch browning and doneness.
Why are oven conversions rounded?
Oven dials and recipes usually use rounded temperatures. The calculator rounds to practical baking increments instead of false precision.
Is gas mark exact?
Gas marks are approximate temperature ranges. The calculator returns the nearest common gas mark for the converted temperature.
