Oven to Air Fryer Conversion Calculator
Enter the oven temperature and time from any recipe and get the air fryer equivalent instantly. It also works in reverse, and in Celsius.
How oven to air fryer conversion works
An air fryer is a small, powerful convection oven. The fan sits close to the food and moves hot air much faster than a full-size oven, so food browns and cooks through sooner. That's why the standard rule is:
- Lower the temperature by 25°F (about 15°C), so the outside doesn't brown before the middle is done.
- Cut the cook time by about 20%. Start checking at around three-quarters of the original time.
- For convection oven recipes, keep the temperature the same and trim the time by about 10%.
Most home air fryers top out at 400°F. If a recipe calls for 450°F or higher, set the air fryer to 400°F and rely on the shorter time instead.

Tips for converting any recipe
- Cook in a single layer. The time savings only work if air can reach every side. Cook large recipes in batches.
- Flip or shake halfway. Air fryers heat mostly from the top, so turning food gives even browning.
- Use a thermometer for meat. Time conversions are estimates, and internal temperature is what makes meat safe. See the safe temperatures table.
- Size matters. Big roasts and whole birds may not fit or may cook unevenly. Anything over about 3–4 lb usually does better in the oven, unless you have a large air fryer oven. For turkey, use our turkey cooking time calculator.
- Watch sugar and cheese. Glazes and cheesy toppings brown fast. Add them in the last few minutes.
Foods that don't convert well
Soups, stews and anything with a lot of liquid, thin wet batters (like tempura or pancake batter without a pan), large casseroles, and big cakes are better in the oven. Light, leafy foods like raw spinach can blow around in the fan. Weigh them down or skip the air fryer.
Frequently asked questions
How do you convert oven time and temperature to an air fryer?
Lower the temperature by 25°F (about 15°C) and reduce the cook time by about 20%. A recipe that bakes at 400°F205°C for 20 minutes becomes about 375°F190°C for 16 minutes in the air fryer. Start checking a few minutes early the first time.
What is 350°F175°C in the oven in an air fryer?
350°F175°C in a conventional oven is about 325°F165°C in an air fryer, for roughly 80% of the original time. For example, 30 minutes at 350°F175°C becomes about 24 minutes at 325°F165°C.
What is 400°F205°C in the oven in an air fryer?
400°F205°C in the oven converts to about 375°F190°C in the air fryer. Cut the time by about 20%, so 25 minutes becomes about 20 minutes.
Is an air fryer the same as a convection oven?
They use the same idea, a fan circulating hot air, but an air fryer is much smaller with a stronger fan, so food cooks faster and crisps more. If a recipe is written for a convection oven, keep the same temperature and reduce the time by about 10%.
How do I convert an air fryer recipe to a regular oven?
Do the reverse: raise the temperature by 25°F and increase the time by about 25%. Air fryer food cooked at 375°F190°C for 16 minutes becomes about 400°F205°C for 20 minutes in a conventional oven.
What is 200°C in Fahrenheit for an air fryer?
200°C is about 390–400°F200–205°C. Most air fryer dials in the US use Fahrenheit, and many models let you switch units in the settings menu, often by holding the temperature buttons together for a few seconds. Check your manual.
Can you convert baking recipes to the air fryer?
Yes, for small batches in an oven-safe pan that fits the basket. Use the same 25°F reduction, check with a toothpick early, and loosely cover the top with foil if it browns before the center sets. Very wet batters and large cakes are better in the oven.
How do I convert a deep fryer recipe to the air fryer?
Air fry breaded or battered foods at 380–400°F195–205°C, lightly sprayed with oil, in a single layer. Most foods that deep fry in 3–5 minutes take 8–15 minutes in the air fryer. Thin wet batters don't work, because they drip before they set, so switch to a flour-egg-breadcrumb coating.
