Convection Oven to Air Fryer Converter
Convection ovens already use a fan, so this adjustment is smaller than a standard oven conversion.
Air fryer setting
That temperature is above your air fryer's maximum, so we capped it and added 10% to the time to compensate.
The 25°F / 20% rule is a widely used convention, not a measured physical constant. We have not tested it in a lab, and no air fryer we know of has been calibrated against it. Treat the result as a starting point and check your food. How we know what we know.
Why the convection adjustment is smaller
A convection oven and an air fryer work on the same principle — a fan circulating hot air. The difference is scale. An air fryer has a much smaller chamber and a more aggressive fan, so air moves faster across the food. The gap is real but far narrower than with a conventional oven, so you only drop 15°F and trim 10% of the time.
Air fryer temp = convection temp − 15°F · Air fryer time = convection time × 0.9
Example. A convection recipe of 375°F for 20 minutes becomes 360°F for 18 minutes in an air fryer.

Common questions
Is an air fryer the same as a convection oven?
Mechanically they are the same idea — a fan circulating hot air. An air fryer is smaller with a faster fan, which concentrates the airflow and cooks food more quickly.
Do you need to adjust convection recipes for an air fryer?
Yes, but only slightly. Lower the temperature by 15°F and reduce the time by around 10%.
Which is better, a convection oven or an air fryer?
An air fryer crisps small batches faster and preheats in a fraction of the time. A convection oven handles far more food at once. For one or two portions the air fryer wins on both speed and texture.
What is 350°F convection in an air fryer?
Set the air fryer to 335°F and cut the time by 10%. A recipe calling for 20 minutes at 350°F convection takes about 18 minutes. The gap is small because both cook with moving hot air.
What is 375°F convection in an air fryer?
Set the air fryer to 360°F and cut the time by 10%. A recipe calling for 20 minutes at 375°F convection takes about 18 minutes. The gap is small because both cook with moving hot air.
What is 400°F convection in an air fryer?
Set the air fryer to 385°F and cut the time by 10%. A recipe calling for 20 minutes at 400°F convection takes about 18 minutes. The gap is small because both cook with moving hot air.
What is 425°F convection in an air fryer?
Set the air fryer to 410°F and cut the time by 10%. A recipe calling for 20 minutes at 425°F convection takes about 18 minutes. The gap is small because both cook with moving hot air.
What is 450°F convection in an air fryer?
Set the air fryer to 435°F and cut the time by 10%. A recipe calling for 20 minutes at 450°F convection takes about 18 minutes. The gap is small because both cook with moving hot air.
