220°C to Fahrenheit — all four oven scales
The exact conversion is °C × 9/5 + 32, so 220°C works out to 428°F. Recipe writers don't use the exact figure: the long-standing pairing puts 220°C alongside 425°F and gas mark 7, and since a home oven swings around its set point by more than the rounding difference, the paired values are interchangeable in practice. Follow whichever scale your dial shows.
In a fan (convection) oven, use 200°C — the standard adjustment is conventional minus 20°C, because moving air transfers heat faster than still air. Make the temperature adjustment or shorten the bake time by about a quarter, never both. Bake times are otherwise unaffected by converting between scales: 220°C and 425°F are the same heat wearing different units.
Where 220°C sits on the chart
| °F | °C | Fan °C | Gas mark | Descriptor |
|---|---|---|---|---|
| 375°F | 190°C | 170°C | 5 | Moderately hot |
| 400°F | 200°C | 180°C | 6 | Moderately hot |
| 425°F | 220°C | 200°C | 7 | Hot |
| 450°F | 230°C | 210°C | 8 | Hot |
| 475°F | 245°C | 225°C | 9 | Very hot |

What bakes at this temperature
425°F / 220°C is the territory of pies, tarts and anything that needs a fast-set crust. Remember that most home ovens swing ±25°F around their set point and many run permanently hot or cold — a standalone oven thermometer on the middle rack tells you more than any conversion chart can.
