The formula
°C = (°F − 32) × 5/9. For oven temperatures, the useful mental shortcut is to subtract 32, halve it, then add 10%: 350 °F → (318 ÷ 2) = 159, plus 10% ≈ 175 °C. The exact answer is 176.7 °C.
Oven anchors worth memorising
- 325 °F = 165 °C (slow bake, custards)
- 350 °F = 177 °C (the default baking temperature)
- 375 °F = 190 °C (cookies, pastry)
- 400 °F = 204 °C (roasting vegetables)
- 425 °F = 218 °C (fast roast, pizza)
Fan ovens
A convection (fan) oven runs about 20 °C hotter than the dial suggests. If a conventional recipe says 180 °C, set a fan oven to 160 °C. Most European ovens label both.
Meat and safety
Oven temperature is not the same as internal temperature. Poultry needs 74 °C internal, ground meat 71 °C, whole cuts of pork 63 °C with rest — use a probe thermometer, not the dial.
Frequently Asked Questions
What is 350 °F in Celsius?
176.7 °C — most recipes round to 175 or 180.
Is 180 °C the same as 350 °F?
Nearly: 180 °C is 356 °F. The 4 °F difference is within oven tolerance.
How do I convert a fan oven temperature?
Subtract 20 °C from the conventional figure.
