Air Fryer Conversion Calculator
Last updated: May 31, 2026
Written by Blake Boege
An air fryer conversion calculator is a kitchen utility that adapts standard baking recipes for convection air frying. It automatically reduces the cooking temperature by 25°F (15°C) and the duration by 20% to account for the faster heat transfer and high air circulation speed typical of countertop air fryers.
Convert standard oven recipes to air fryer time and temperature settings automatically.
Quick Answer
Convert conventional oven cooking temperatures and times to air fryer settings using the 25°F/15°C temp reduction and 20% time reduction rules.
Conversion Direction
Temperature Unit
Air Fryer Settings
375°F for 16 mins
Rule of thumb: reduce temp by 25°F/15°C and time by 20% for air frying.
Common Food Conversion Table
| Food Item | Standard Oven Recipe | Estimated Air Fryer Settings |
|---|---|---|
| Chicken wings | 400°F (200°C) / 30m | 375°F (190°C) / 24m |
| French fries | 425°F (220°C) / 25m | 400°F (200°C) / 20m |
| Bacon | 400°F (200°C) / 15m | 375°F (190°C) / 12m |
| Salmon | 400°F (200°C) / 15m | 375°F (190°C) / 12m |
| Brussels sprouts | 400°F (200°C) / 25m | 375°F (190°C) / 20m |
| Frozen nuggets | 400°F (200°C) / 15m | 375°F (190°C) / 12m |
How it works
How Oven to Air Fryer Conversion Works
Because air fryers circulate high-heat air directly and closely around your food, they cook much faster and more intensely than a conventional bake oven. To prevent burning your food while ensuring it cooks all the way through, you must adjust both the temperature and the duration.
The 25°F (15°C) Temperature Rule
Lower the temperature of your target recipe. This ensures the exterior of your food does not burn before the interior is fully cooked:
- Fahrenheit: Air Fryer Temp = Oven Temp − 25°F
- Celsius: Air Fryer Temp = Oven Temp − 15°C
The 20% Time Reduction Rule
Multiply the conventional oven cooking time by 0.8 (a 20% reduction) to find the estimated air fryer cooking duration:
Air Fryer Time = Math.round(Oven Time × 0.8)
Conversely, if you want to convert an air fryer setting back to a standard oven, divide the time by 0.8.
Practical Tips for Air Frying
- Don't Overcrowd the Basket: Air fryers rely on free air circulation. If you stack food in layers, it will steam instead of fry. Cook in batches if necessary.
- Shake or Flip Halfway: Gently shake the basket or flip items like chicken wings or fries midway through cooking to ensure even browning and crispiness.
- Check Early: Air fryers vary widely in power. Always check your food 2 to 3 minutes before the estimated time is up to ensure it doesn't overcook.

Frequently asked questions
The standard rule of thumb is to reduce the recipe's recommended oven temperature by 25°F (or 15°C) and decrease the cooking time by 20%. For example, if a recipe calls for baking at 400°F for 20 minutes, you should air fry at 375°F for about 16 minutes.
Air fryers are compact convection ovens. They use a powerful fan to circulate hot air rapidly around the food in a small space. This intense circulation heats food more efficiently, evaporates surface moisture faster, and cooks food in about 80% of the time required by a standard oven.
Yes, preheating for 2 to 3 minutes ensures that the air fryer starts cooking at the correct temperature immediately. This is especially important for getting a crispy exterior on meats, fries, and frozen snacks.
Yes, but you must ensure it is weighed down by food so it doesn't fly into the heating element. Also, do not block the entire basket flow, as air circulation is critical for even cooking in an air fryer.
To convert air fryer settings to a standard oven, increase the temperature by 25°F (15°C) and divide the time by 0.8 (which increases the cooking duration by 25%). For example, 16 minutes in an air fryer becomes 20 minutes in a standard oven.
