The formula
- Air fryer temperature = oven temperature − 25°F (or − 15°C), rounded to the nearest 5°.
- Air fryer time = oven time × 0.8 (20% less). By food type: Most recipes × 0.8, Thin & crispy × 0.75, Vegetables × 0.75, Thick meat & roasts × 0.85, Cakes & bakes × 0.85, Frozen food × 0.8.
- Check at = oven time × 0.75, rounded down.
Worked example: 400°F − 25°F = 375°F · 25 min × 0.8 = 20 min · check at 18 min
Results above 400°F (200°C) get a warning, because many basket air fryers stop there. Method version 1.1. Why these numbers: methodology.
220°C oven to air fryer time chart
Every row below is 220°C in the oven and 205°C in the air fryer. The time cut depends on the food: thin, crispy foods finish sooner, while thick meat and cakes need closer to their full time.
| Oven at 220°C | Most recipes | Thin & crispy | Thick meat & bakes | Check at |
|---|---|---|---|---|
| 10 min | 8 min | 8 min | 9 min | 7 min |
| 15 min | 12 min | 11 min | 13 min | 11 min |
| 20 min | 16 min | 15 min | 17 min | 15 min |
| 25 min | 20 min | 19 min | 21 min | 18 min |
| 30 min | 24 min | 23 min | 26 min | 22 min |
| 40 min | 32 min | 30 min | 34 min | 30 min |

| 60 min | 48 min | 45 min | 51 min | 45 min |
220°C in Fahrenheit, fan and gas mark
| Conventional oven | 220°C = 428°F (recipes use 425°F) |
|---|---|
| Fan / convection oven | 405°F / 205°C fan |
| Gas oven | Gas mark 7 |
| Air fryer | 205°C / 400°F |
The fan figure uses the same rule as the air fryer, because both cook with moving air. If a recipe already gives a fan or convection temperature, use it in the air fryer unchanged and only shorten the time by about 10%: see convection oven to air fryer or fan oven to air fryer.
Why 220°C becomes 205°C
An air fryer is a small convection oven with a powerful fan. Moving air carries heat into food faster than the still air of a regular oven, so the same browning happens at a lower setting:220°C − 15°C = 205°C. The result is rounded to the nearest 5 degrees to match air fryer dials.
Foods often cooked at 220°C

- Frozen egg rolls: oven 425°F for 15 min
- Pork chops: oven 425°F for 15 min
- Chicken cutlets: oven 425°F for 13 min
- Chicken wings: oven 425°F for 35 min
- Bagel Bites: oven 425°F for 13 min
- Frozen hash brown patties: oven 425°F for 16 min

Accuracy and limitations
The arithmetic is exact: the same function produces the calculator result, every chart on this site and the printable chart. The cooking result is an estimate, because the formula cannot see your appliance or your food.
- Appliances vary. Wattage, basket size and how close the element sits to the food change cooking speed. That’s why every result includes a “check at” time.
- Load matters. A full or stacked basket cooks more slowly than a single layer.
- Temperature limits. Many basket air fryers stop at 400°F (200°C). Converted settings above that are flagged.
- Poor fits for any formula: wet batters, delicate cakes, low-and-slow recipes and roasts over an hour. Use a thermometer and expect to adjust.
- Food safety comes from internal temperature, not time. Check meat, poultry, seafood and leftovers against the USDA safe minimum temperatures.

Frequently asked questions
What is 220°C in an air fryer?
A recipe written for a 220°C conventional oven converts to 205°C (about 400°F) in the air fryer, with the cooking time multiplied by 0.8. Many basket air fryers top out at 200°C; if yours can’t reach 205°C, use its maximum and check early. If the recipe already gives an air fryer temperature, keep it as it is.
How long is 20 minutes at 220°C in an air fryer?
About 16 minutes at 205°C. Start checking at 15 minutes; thin, crispy foods may be done sooner and thick cuts may need the full time.
What is 220°C in Fahrenheit?
220°C is exactly 428°F. Recipes usually treat it as 425°F. On a gas oven it is about gas mark 7.
What is 220°C in a fan oven?
Lower it by 15°C to about 205°C (405°F) fan. A fan or convection oven circulates air like an air fryer, so a fan temperature goes straight into the air fryer unchanged.
What is a 220°C air fryer recipe in the oven?
Going the other way, a 220°C air fryer recipe needs about 235°C in a conventional oven, with the time multiplied by 1.25.
