Oven and air fryer converters
By AnoyUpdated Last reviewed How we calculate
Pick the oven your recipe was written for. Conventional, gas and standard toaster ovens all use the same rule (−25°F / −15°C, time × 0.8). Convection and fan ovens keep the temperature and take about 10% off the time.

- Air fryer to oven conversionAdd 25°F (15°C), time × 1.25.

Which converter do I need?
- Recipe says “bake” or “oven” with no mention of fan: it is a conventional oven. Use oven to air fryer.
- Recipe gives a “fan” temperature (UK, Australia): use fan oven to air fryer.
- Recipe gives a gas mark: use gas oven to air fryer.
- You have an air fryer recipe but want to use the oven: use air fryer to oven.
