Almost every recipe ever printed was written for a regular oven. This calculator turns those oven numbers into air fryer numbers in one click: type in the recipe’s temperature and time, and you get the air fryer setting, in Fahrenheit and Celsius, with a time range and a “start checking” point so nothing overcooks.
Oven to Air Fryer Calculator
Type in your oven recipe’s temperature and time — the air fryer setting appears instantly.
Your Air Fryer Setting
Air fryer: 375°F (190°C)
Time: about 22 minutes to 24 minutes (oven said 30 minutes — you save about 6 minutes)
Start checking at 19 minutes — every air fryer runs a little different.
Flip or shake the basket halfway through — air fryers cook fastest on the side facing the fan.
Uses the standard conversion — lower temperature, less time — adjusted for your food and your machine type. Every air fryer runs a little different, so treat the result as a strong starting point and check early the first time.
Built by Fliss Wright. This calculator uses the same conversion as every recipe on this site, and the food-by-food adjustments below come from the way those recipes are actually timed.*

How to Use This Calculator
- Type the oven temperature from your recipe. Use the °F / °C button if your recipe is in Celsius.
- Type the oven time in minutes, exactly as the recipe says.
- Pick your oven type. A fan or convection oven already moves hot air around, so it needs a smaller adjustment than a conventional oven.
- Pick what you are cooking. Most foods follow the standard rule. Cakes, cookies and baking get a bigger temperature drop, because the top browns fast in an air fryer.
- Read your answer. It appears instantly and updates as you change anything. Cook at the temperature shown, start checking at the time shown, and flip or shake the food halfway.
The Method Behind the Numbers
An air fryer is a small convection oven: a strong fan pushes hot air around food in a tight space. Heat reaches the food faster than in a big oven, so the same recipe needs a lower temperature and less time. The standard conversion, the one used by almost every test kitchen, is:
- Temperature: 25°F lower (about 15°C lower) than the oven recipe says.
- Time: about 20% less than the oven recipe says.
So a recipe written at 400°F (205°C) for 30 minutes becomes 375°F (190°C) for about 24 minutes in the air fryer. This calculator does that math for you, then adjusts it:
- Fan / convection oven recipes already bake with moving air, so the temperature drop is smaller, about 10°F (5°C).
- Cakes and cookies brown on top very quickly under the fan, so they get a 50°F (30°C) drop from a conventional oven.
- Low oven temperatures (below 325°F / 165°C) get a gentler 20°F drop, because small differences matter more at low heat.
- Very high temperatures are capped at 400°F (205°C). Most air fryers simply do not go higher, so the calculator holds the temperature at 400°F and adds a few minutes instead.

Quick Chart: The Temperatures Everyone Uses
| Oven | Air Fryer | Example Time |
|---|---|---|
| 350°F (175°C) | 325°F (160°C) | 30 min → 24 min |
| 375°F (190°C) | 350°F (175°C) | 25 min → 20 min |
| 400°F (205°C) | 375°F (190°C) | 30 min → 24 min |
| 425°F (220°C) | 400°F (205°C) | 20 min → 16 min |
These four cover most recipes. Anything else follows the same rule: 25°F less heat, and about a fifth less time.
Worked Examples
- Frozen snacks from a package that says 400°F for 20 minutes: this is exactly how our air fryer frozen potstickers style recipes are timed. The calculator gives 375°F (190°C) and 15 to 16 minutes.
- A cake written at 350°F (175°C) for 35 minutes becomes 300°F (150°C) for about 26 to 28 minutes. Start checking early; cakes go from golden to dark quickly.
- Roast vegetables written at 425°F (220°C) for 40 minutes become 400°F (205°C) for about 30 to 32 minutes, with a shake halfway.

Converting Back: Air Fryer to Oven
The switch at the top of the calculator also runs the other way. If a recipe was written for the air fryer and you want to bake it in a regular oven instead, tap Air Fryer → Oven and type the air fryer numbers in. The rule reverses: add 25°F (15°C) to the temperature and add about 25 percent to the time. An air fryer recipe at 375°F (190°C) for 20 minutes becomes about 400°F (205°C) for 25 minutes in the oven. Cakes and bakes go up by 50°F (30°C), the mirror image of the drop they get on the way in. Use the middle rack, and expect slightly softer edges than the air fryer gives.
Settings From Our Own Recipes
No conversion needed for these — they were written for the air fryer from the start, at the exact settings our recipes use:
| Recipe | Temperature | Time |
|---|---|---|
| Frozen potstickers | 380°F (190°C) | 10 min |
| Frozen shrimp | 400°F (205°C) | 10 min |
| Frozen Texas toast | 370°F (190°C) | 8 min |
| Frozen taquitos | 380°F (190°C) | 8–10 min |
When a Converted Recipe Goes Wrong
Dark outside, raw inside almost always means the temperature was too high or the basket was crowded. Drop another 10°F (5°C), cook a little longer, and give the food space: hot air needs room to move, which is also why a single layer matters more than the exact number on the dial.
Cooked but not crispy usually means moisture. Pat the food dry before it goes in, do not skip the halfway shake, and finish with 2 extra minutes at 400°F (205°C) for a final crisp.
Done way before the calculator's time happens with small or thin foods and with powerful models. That is why every result includes a "start checking" time. After two or three cooks you will know your own machine's habit, and you can trust your numbers over any calculator, including this one.
