The formula

Fahrenheit = Celsius × 1.8 + 32. Recipes round to the nearest 25°F, so small differences are normal.

Fan ovens

Fan ovens run hotter. Many recipes suggest lowering the temperature by about 20°C for a fan oven, so check your oven’s manual.

When a live helper is useful

A cook on video can see how your bake is browning and tell you whether your oven runs hot.
