Set your oven to this

No oven dial has a 212 °F mark. Recipes treat 100 °C and 225 °F as the same setting — gas mark ¼ — and the gap between them is smaller than the swing of a domestic thermostat. Set a fan-forced oven to 80 °C.

100 °C is the boiling point of water at sea level, and at the very bottom of the oven dial it is the setting for drying meringues, dehydrating fruit and holding cooked food at temperature.

Questions

Frequently asked questions

What is 100 °C in Fahrenheit?
100 °C is exactly 212 °F. As an oven setting, use 225 °F — the dial mark recipes mean, which is gas mark ¼. In a fan oven, set 80 °C.
Is 100 °C the same as 212 °F?
Yes, exactly — this is the one point on the scale where the conversion is a round, familiar number in both units. 100 °C is the boiling point of water at sea level.
Does water always boil at 100 °C?
Only at sea level. Boiling point falls with altitude — roughly 1 °C for every 300 m — which is why high-altitude recipes extend simmering times.
