🌡️ Temperature & ovens
325 °F to °C
325 °F is 162.8 °C. Subtract 32, multiply by 5 and divide by 9. On a fan oven, set about 143 °C.
The short answer
325 °F = 162.8 °C
Fan oven: 143 °C. This is a moderate oven.
About 325 °F in °C
325 °F is 162.8 °C. The formula is (F − 32) × 5/9: 325 − 32 = 293, then 293 × 5 ÷ 9 = 162.8. 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 325 °F instruction becomes 143 °C on a fan setting. If your oven only has round numbers, choose the nearest (160 °C) and adjust the time by about 10%.
A 325 °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: 325 °F, 163 °C and a gas mark all describe one oven heat, and British recipes still print two of the three side by side. Converting 325 °F to 163 °C and then to a fan setting of 143 °C keeps the recipe's intent even when your oven runs a little hot.
Recipe apps often write the question as 325 f to c rather than with degree symbols, and the answer is the same: 162.8 c. Rounded to 163 c, that is what most oven dials can actually be set to.
How the calculation works
- (325 °F − 32) × 5/9 = 162.8 °C
- Fan oven: 162.8 − 20 = 142.8 °C
- Reverse: (162.8 °C × 9/5) + 32 = 325 °F
