Understanding the Air Fryer Calculator

An air fryer cooks by circulating hot air, so recipes written for a conventional oven need adjusting. This calculator converts oven temperature and time into air fryer settings, helping you get crispy, evenly cooked results without burning the outside or leaving the inside underdone.

The general conversion rule

A common starting point is to lower the oven temperature by about 25°F (roughly 15°C) and reduce the cooking time by around 20%, because the air fryer’s rapid air circulation cooks faster and more efficiently. These are starting points — the first time you make a dish, check it early to learn how your specific model behaves.

Why models vary

Air fryers differ in wattage and basket size, so the same setting can cook differently from one machine to another. Avoid overcrowding the basket, which blocks airflow and leads to soggy results, and shake or flip food partway through for even browning. Treat the calculator as a reliable guide you fine-tune to your own appliance.

Tips & things to know

  • Lower oven temperature by about 25°F and cut time by roughly 20%.
  • Do not overcrowd the basket — airflow is what creates crispiness.
  • Check food early the first time you make a dish.

How It Works

Air fryers cook faster because they circulate hot air in a compact space. The standard conversion is:

Air Fryer Temp = Oven Temp − 25°F

Air Fryer Time = Oven Time × 0.80 (20% reduction)

Worked Example

Oven: 400°F for 20 min → Air Fryer: 375°F for 16 min

Frequently Asked Questions

How do I convert oven to air fryer?

Reduce the oven temperature by 25°F and the cooking time by 20%. Our calculator does this conversion instantly for any recipe.

Do I need to preheat my air fryer?

Yes, preheating for 3-5 minutes helps achieve more even cooking and better browning, similar to preheating an oven.

Why does air fryer cook faster?

Air fryers use rapid air circulation in a small chamber, delivering heat more efficiently to food than a full-sized oven.

Can I use aluminum foil in air fryer?

Yes, but only in the basket (never blocking airflow). Parchment paper liners designed for air fryers are a better option.

Do all foods work in an air fryer?

Most foods work great, especially breaded items and vegetables. Avoid wet batters, very large items, and delicate foods like soft fish.
