🌡️ Temperature & ovens
450 °F to °C
450 °F is 232.2 °C. Subtract 32, multiply by 5 and divide by 9. On a fan oven, set about 212 °C.
The short answer
450 °F = 232.2 °C
Fan oven: 212 °C. This is a very hot oven.
About 450 °F in °C
450 °F is 232.2 °C. The formula is (F − 32) × 5/9: 450 − 32 = 418, then 418 × 5 ÷ 9 = 232.2. Celsius and Fahrenheit cross at − 40, not at zero, which is why the subtraction comes first.
Fan ovens run about 20 °C cooler than the temperature written on a conventional recipe, so a 450 °F instruction becomes 212 °C on a fan setting. If your oven only has round numbers, choose the nearest (230 °C) and adjust the time by about 10%.
A 450 °F oven is in the very hot band — roughly gas mark 8-9. That matters more than the exact degree: a 10 °C error changes a sponge by a couple of minutes, while the wrong band changes whether the outside browns before the middle sets.
Gas marks are a third scale in the same kitchen: 450 °F, 232 °C and a gas mark all describe one oven heat, and British recipes still print two of the three side by side. Converting 450 °F to 232 °C and then to a fan setting of 212 °C keeps the recipe's intent even when your oven runs a little hot.
Recipe apps often write the question as 450 f to c rather than with degree symbols, and the answer is the same: 232.2 c. Rounded to 232 c, that is what most oven dials can actually be set to.
How the calculation works
- (450 °F − 32) × 5/9 = 232.2 °C
- Fan oven: 232.2 − 20 = 212.2 °C
- Reverse: (232.2 °C × 9/5) + 32 = 450 °F
