Convection Oven to Air Fryer Converter
Enter your convection oven recipe settings below.
Convection recipes convert gently: drop only 10°F and trim about 15% of the time. Check a few minutes early on the first cook.
Converting from a regular (non convection) oven? Use the main oven to air fryer calculator. British and Australian cooks call this appliance a fan oven, and the fan oven to air fryer page covers the same conversion Celsius first.
Why Convection Converts Differently Than Conventional
The standard oven to air fryer rule, minus 25°F and minus 20% time, assumes the recipe was written for a conventional oven with still air. A convection oven breaks that assumption. Its fan already circulates heat, which is why convection recipes run about 25°F cooler than conventional versions of the same dish. Apply the full standard reduction on top and you subtract the airflow benefit twice, ending with food that needs rescue minutes added back by guesswork.
The correct convection to air fryer conversion is modest: reduce the temperature by about 10°F (5°C) and the time by roughly 15%. A convection recipe at 375°F for 25 minutes becomes about 365°F, in practice 360 or 365 on most dials, for 21 minutes in the air fryer. The air fryer still wins on intensity because its chamber is small and its fan is close to the food, but the gap between convection and air fryer is a step, not the staircase between conventional and air fryer.
Convection Bake vs Convection Roast Settings
Many American ranges offer both convection bake and convection roast. Convection bake uses gentler fan speed and converts exactly as described above. Convection roast runs the fan harder and often engages the top element, sitting even closer to air fryer behaviour, so convert it with no temperature drop at all and just trim 10% of the time. If your recipe just says "convection", treat it as convection bake. And if you are unsure whether the original recipe was convection or conventional at all, the full conversion chart covers the conventional case.

Common convection settings with their air fryer equivalents.
| Convection Oven (°F) | Air Fryer (°F) | Convection Oven (°C) | Air Fryer (°C) |
|---|---|---|---|
| 300°F | 290°F | 150°C | 145°C |
| 325°F | 315°F | 165°C | 160°C |
| 350°F | 340°F | 175°C | 170°C |
| 375°F | 365°F | 190°C | 185°C |
| 400°F | 390°F | 200°C | 195°C |
| 425°F | 400°F | 220°C | 200°C |
Time rule for all rows: reduce the convection recipe time by about 15%.
Convection to Air Fryer: Frequently Asked Questions
Reduce the temperature by about 10°F (5°C) and the cooking time by roughly 15%. Convection ovens already circulate air, so they need a much smaller reduction than conventional oven recipes, which drop 25°F and 20% of the time.
They share the principle of circulated hot air, but the air fryer's compact chamber and close, powerful fan move air across the food several times faster. That is why food crisps harder and cooks slightly quicker in an air fryer even compared with convection.
Yes. Convection oven is the North American name and fan oven is the British and Australian name for the same appliance. Both convert to the air fryer with the same gentle rule. The fan oven page on this site covers it Celsius first for UK style recipes.
Convection roast runs its fan harder than convection bake and behaves very close to an air fryer already. Keep the same temperature and trim only about 10% of the time. For convection bake or plain convection recipes, use the standard rule on this page.
