How this calculator works
Enter your oven’s temperature and cook time, and this calculator applies the standard air fryer conversion rule to estimate the equivalent air fryer settings.
The formula
airFryerTemp(°F) = ovenTemp(°F) − 25 airFryerTemp(°C) = ovenTemp(°C) − 15 airFryerTime = ovenTime × 0.8
Worked example
An oven recipe calling for 400°F for 20 minutes:
- Air fryer temperature: 400 − 25 = 375°F
- Air fryer time: 20 × 0.8 = 16 minutes
Common food presets
| Food | Oven | Air Fryer |
|---|---|---|
| French fries (frozen) | 425°F, 25 min | 400°F, 20 min |
| Chicken breast | 400°F, 25 min | 375°F, 20 min (internal 165°F) |
| Salmon fillet | 400°F, 15 min | 375°F, 12 min (internal 145°F) |
| Frozen chicken nuggets | 400°F, 18 min | 375°F, 14 min (internal 165°F) |
Safe minimum internal temperatures (USDA): poultry 165°F, fish 145°F. Always verify with a food thermometer.
Frequently asked questions (FAQ)
Why do air fryer recipes use a lower temperature and shorter time?
An air fryer is essentially a small, powerful convection oven: its compact size and fast-moving hot air cook food more efficiently than a full-size oven, so the same result needs less heat and less time.
Is this conversion exact for every food?
No. It's a reliable starting point (a widely used rule of thumb), but actual results vary by air fryer model, food thickness, and whether you're cooking from frozen or fresh. Check food a few minutes before the converted time is up, especially the first time you try a recipe.
What's a safe internal temperature for chicken?
165°F (74°C), per USDA guidelines. This applies to whole chicken, chicken breasts, and ground chicken alike. Always verify with a food thermometer rather than relying on cook time alone.
Do I need to preheat an air fryer?
Many air fryers cook well without preheating, unlike conventional ovens, though preheating for 2-3 minutes can improve crispiness for some foods. Check your specific air fryer's manual for its recommendation.
Why does my air fryer food come out different than the oven version?
Air fryers circulate hot air much more intensely in a smaller space, which browns and crisps surfaces faster than a conventional oven. That's great for crispy exteriors, but it means food can dry out if left in too long. Start with the converted time and check early.
