Figures are the rounded values used on recipes and oven dials.
The formula
Fahrenheit = Celsius × 9 ÷ 5 + 32. For Celsius, subtract 32 and multiply by 5 ÷ 9.
Fan ovens and hot spots
Fan ovens circulate air and cook faster, so lower the temperature by about 20°C. Every oven runs a little differently, so check bakes a few minutes early the first time.
When a live helper is useful
A baker on video can look at your bake and tell you whether your oven runs hot.
