350 °F 176.67 °C

425 °F 218.33 °C

To convert Fahrenheit to Celsius, subtract 32 and divide by 1.8. Room temperature at 72 °F is 22.2 °C, a 350 °F oven is 176.7 °C, and 98.6 °F is 37 °C. The order matters: subtracting after dividing gives an answer that is wrong by about eighteen degrees.

How to convert °F to °C

1 Type the Fahrenheit temperature.

2 Read the Celsius value, rounded however you like.

3 Press ⇄ to convert Celsius back to Fahrenheit.

Recipes are where this matters most, and where rounding is normal. American baking temperatures of 325, 350, 375 and 425 °F become 163, 177, 191 and 218 °C, which European recipes round to 160, 180, 190 and 220. A fan oven then wants about 20 °C less again, so a 350 °F recipe is 160 °C fan.
