Air Fryer Conversion Calculator
Enter the oven temperature and time from any recipe and get the equivalent air fryer setting. The calculator applies the widely used conversion rule — lower the temperature by 25°F and shorten the time by about 20% — and rounds to settings you can actually dial in.
How the oven-to-air-fryer conversion works
Air fryers are small convection ovens. Because the heating element sits close to the food and a fan moves hot air quickly through a compact basket, food browns and cooks noticeably faster than in a conventional oven set to the same temperature. The conversion used by appliance manufacturers and recipe developers alike is simple:
- Temperature: reduce by 25°F (about 15°C).
- Time: reduce by about 20%, then check early.
This calculator also rounds the result to the nearest 5°F and whole minute, because that is what air fryer dials and keypads accept. Treat the output as your starting point: basket size, food load, and wattage (usually 1,200–1,800 W) all shift real-world timing by a few minutes.
Tips for better air fryer results
- Don’t overcrowd. Hot air needs to reach every surface; cook in batches for real crispiness.
- Shake or flip halfway. Especially fries, wings, and vegetables.
- Use a light oil spray on breaded foods — it replaces the browning that deep frying would give.
- Trust a thermometer, not the clock, for any meat, poultry, or fish.
Frequently asked questions
How do I convert an oven recipe to an air fryer?
Reduce the oven temperature by 25°F and cut the cooking time by about 20%. A recipe that calls for 400°F for 20 minutes in the oven becomes roughly 375°F for 16 minutes in the air fryer. Start checking a few minutes early — air fryer baskets and wattages vary.
Why do air fryers cook faster than ovens?
An air fryer is a compact convection oven: a fan circulates hot air at high speed in a small chamber, so heat reaches the food surface faster and more evenly than in a large, mostly still oven cavity. That faster heat transfer is why you drop both temperature and time.
Do I need to preheat an air fryer?
Most models benefit from 2–3 minutes of preheating for crispy results, especially for frozen foods and breaded items. Some manufacturers say it is optional — when in doubt, preheat briefly and check food early.
Is the 25°F / 20% rule safe for meat and poultry?
The rule adjusts cooking conditions, not food-safety targets. Always confirm doneness with an instant-read thermometer: poultry to 165°F, ground meat to 160°F, and whole cuts of beef or pork to 145°F with a 3-minute rest, per USDA guidance.
What should I not cook in an air fryer?
Wet batters (they drip through the basket before setting), large roasts that block airflow, and delicate leafy greens that blow around. Everything breaded, most vegetables, and most frozen convenience foods convert beautifully.
