Air Fryer Converter

About the Air Fryer Converter

Air fryers cook faster and hotter than a conventional oven at the same temperature setting, because they circulate hot air much more aggressively. Using a conventional oven recipe's time and temperature unmodified in an air fryer routinely overcooks or burns the food.

How It Works

The calculator applies the standard air fryer adjustment most manufacturers recommend: drop the temperature by about 25°F (or roughly 14°C) and cut the cook time by about 20%, then shows both the adjusted settings and the original for reference.

Air fryer temp = oven temp − 25°F (or −14°C); air fryer time = oven time × 0.8

Examples

Roasting vegetables

A recipe calling for 400°F for 30 minutes in a conventional oven converts to about 375°F for 24 minutes in an air fryer.

Reheating frozen food

Package instructions of 425°F for 20 minutes become roughly 400°F for 16 minutes - noticeably faster than package directions written for a conventional oven.

Advantages

Applies the same standard adjustment ratio most air fryer manufacturers publish
Works with either Fahrenheit or Celsius input
Shows the original setting alongside the converted one for easy comparison

Common Mistakes

Using the exact oven time and temperature unmodified in an air fryer
Not checking food early the first time a specific recipe is converted
Assuming every air fryer model behaves identically

Edge Cases to Watch For

Foods that need a specific internal temperature for food safety (poultry, ground meat) should always be checked with a food thermometer rather than relying on adjusted time alone.
Very thin or small items (fries, chicken tenders) may need an even bigger time reduction than the standard 20%, since they have less mass to heat through.
Air fryer models vary significantly in actual airflow and calibration, so the first time you convert a specific recipe, check for doneness a few minutes early.

Common Use Cases

Adapting a favorite conventional oven recipe for an air fryer
Converting frozen food package directions written for a conventional oven
Comparing air fryer and oven cook times before deciding which to use

Frequently asked questions

Why lower the temperature for an air fryer?

Air fryers circulate hot air much more aggressively than a conventional oven, cooking food faster at the same temperature - dropping the set temperature by about 25°F (14°C) and shortening the time by roughly 20% compensates for that, which is the standard adjustment most air fryer manufacturers recommend.

Does this work for all foods?

It's a reliable starting point for most oven recipes (roasted vegetables, frozen foods, baked goods), but foods that need a specific internal temperature (like meat) should still be checked with a food thermometer rather than relying on time alone.

Conclusion

The 25°F-cooler, 20%-shorter rule is the standard starting point for converting almost any conventional oven recipe to an air fryer. It won't be perfect for every dish on the first try, but it gets close enough that checking for doneness a few minutes early is all that's usually needed.
