🌡️ Temperature & ovens
180 °F to °C
180 °F is 82.2 °C. Subtract 32, multiply by 5 and divide by 9. On a fan oven, set about 62 °C.
The short answer
180 °F = 82.2 °C
Fan oven: 62 °C. This is a very low oven.
About 180 °F in °C
180 °F is 82.2 °C. The formula is (F − 32) × 5/9: 180 − 32 = 148, then 148 × 5 ÷ 9 = 82.2. 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 180 °F instruction becomes 62 °C on a fan setting. If your oven only has round numbers, choose the nearest (80 °C) and adjust the time by about 10%.
A 180 °F oven is in the very low band — roughly gas mark ¼. 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: 180 °F, 82 °C and a gas mark all describe one oven heat, and British recipes still print two of the three side by side. Converting 180 °F to 82 °C and then to a fan setting of 62 °C keeps the recipe's intent even when your oven runs a little hot.
Recipe apps often write the question as 180 f to c rather than with degree symbols, and the answer is the same: 82.2 c. Rounded to 82 c, that is what most oven dials can actually be set to.
How the calculation works
- (180 °F − 32) × 5/9 = 82.2 °C
- Fan oven: 82.2 − 20 = 62.2 °C
- Reverse: (82.2 °C × 9/5) + 32 = 180 °F
