🌡️ Temperature & ovens
350 °F to °C
350 °F is 176.7 °C. Subtract 32, multiply by 5 and divide by 9. On a fan oven, set about 157 °C.
The short answer
350 °F = 176.7 °C
Fan oven: 157 °C. This is a moderate oven.
About 350 °F in °C
350 °F is 176.7 °C. The formula is (F − 32) × 5/9: 350 − 32 = 318, then 318 × 5 ÷ 9 = 176.7. 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 350 °F instruction becomes 157 °C on a fan setting. If your oven only has round numbers, choose the nearest (180 °C) and adjust the time by about 10%.
A 350 °F oven is in the moderate band — roughly gas mark 4. 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: 350 °F, 177 °C and a gas mark all describe one oven heat, and British recipes still print two of the three side by side. Converting 350 °F to 177 °C and then to a fan setting of 157 °C keeps the recipe's intent even when your oven runs a little hot.
Recipe apps often write the question as 350 f to c rather than with degree symbols, and the answer is the same: 176.7 c. Rounded to 177 c, that is what most oven dials can actually be set to.
How the calculation works
- (350 °F − 32) × 5/9 = 176.7 °C
- Fan oven: 176.7 − 20 = 156.7 °C
- Reverse: (176.7 °C × 9/5) + 32 = 350 °F
