475 °F to Celsius (Oven Temperature)
475 °F equals 246.1 °C — in practice, set a metric oven to 250 °C. Ovens cycle several degrees around their setpoint, so the rounded temperature bakes identically.
| Celsius (conventional) | 246.1 °C → use 250 °C |
|---|---|
| Fahrenheit | 475 °F |
| Fan / convection | about 230 °C (450 °F) |
| Gas mark | 9 (very hot) |
Why fan ovens are set 20 °C lower
A fan (convection) oven moves hot air across the food, transferring heat faster at the same temperature. The standard adjustment is minus 20 °C (about 25 °F) from the conventional temperature — or keep the temperature and shorten the time by roughly a quarter. Recipes written "180 °C fan" already include the reduction.
