Getting the heat right at home
- Fan or convection mode: set about 20 °C lower than the recipe says, or check a few minutes early.
- Preheat: give the oven 10 to 15 minutes to reach the temperature before the tin goes in.
- Middle rack: bake cakes and cookies in the middle, with both rods on in an OTG unless the recipe says otherwise.
- Dials can be wrong: small ovens often run hotter or cooler than the dial. If your cakes brown too fast every time, lower the dial by 10 °C. An oven thermometer settles the question.
- Do not open the door early: a cake needs about two-thirds of its baking time before the door is opened.
The formula
Fahrenheit = Celsius × 9 ÷ 5 + 32. Celsius = (Fahrenheit − 32) × 5 ÷ 9. Recipes round the result to the nearest 25 °F or 10 °C, which is why 180 °C is written as 350 °F.
Questions people ask
What is 180 degrees Celsius in Fahrenheit?
180 °C is 356 °F, which recipes round to 350 °F. It is gas mark 4, the usual temperature for cakes.
Do I reduce the temperature in a fan oven?
Yes, usually by about 20 °C, because the moving air cooks faster. If your oven manual gives its own advice, follow that.
What is a gas mark?
It is the dial numbering on gas ovens in the United Kingdom and some other countries. Gas mark 4 is about 180 °C, and each mark up or down is roughly 10 to 20 °C.
How long should I preheat an OTG?
Ten to fifteen minutes at the baking temperature is enough for most small ovens. A cake put into a cold oven rises unevenly.
