About the Air Fryer Conversion
Enter an oven recipe's temperature (°C or °F) and cooking time. The calculator gives the air fryer temperature and time, and when to start checking.
An air fryer is a small, powerful convection oven, so food cooks faster and browns more. The common rule is to lower the temperature by about 20 °C (25 °F) and cut the time by about 20%, checking early. Don't overcrowd the basket, and adjust for your model; many air fryers max out at 200–230 °C.
The formula
Air fryer temp ≈ oven − 20 °C; time ≈ oven time × 0.8
Worked example
An oven recipe at 400 °F for 30 minutes
- Lower by about 20 °C: 364 °F
- Cut the time by 20%: about 24 minutes
- Check from 18 minutes
