Air Fryer Conversion Calculator

Most food packaging only lists conventional oven instructions, not air fryer settings. This free air fryer conversion calculator instantly handles the oven to air fryer conversion for you — enter the temperature and time from the packet, and this air fryer converter works out exactly what to set your machine to. A full air fryer conversion chart is included further down the page for quick reference too.

What Is an Air Fryer Conversion Calculator?

Air fryers have become hugely popular because they're quicker, more energy-efficient, and cheaper to run than a conventional oven. The catch is that most food manufacturers still only print standard oven instructions on their packaging — they haven't caught up with how many kitchens now cook. An air fryer conversion calculator bridges that gap: you enter the oven temperature and time exactly as printed on the box, and it instantly works out the correct air fryer converter settings, in both degrees and minutes.

How the Oven to Air Fryer Conversion Formula Works

Air fryers are essentially small, powerful convection ovens. Their compact size and fast-moving hot air mean food cooks hotter and faster than it would in a full-sized conventional oven. To get the same result without burning or overcooking your food, this calculator applies a straightforward, widely-used rule of thumb:

  • Reduce the temperature by 40°C compared to the standard oven instructions.
  • Reduce the cooking time by 20% compared to the standard oven instructions.

For example, food that calls for 200°C for 10 minutes in a conventional oven converts to 160°C for 8 minutes in an air fryer, and 220°C for 17 minutes converts to 180°C for 14 minutes. This air fryer converter applies that exact conversion to whatever temperature and time you select, so you get consistent, repeatable results every time.

This is a general-purpose guideline that works well for most everyday foods (frozen snacks, chicken, vegetables, baked goods). Because air fryer models vary in power, always keep an eye on food the first time you cook it with converted settings, and adjust slightly if needed.

Why Do Air Fryers Need Shorter Times and Lower Temperatures?

An air fryer is essentially a small, high-speed convection oven in a compact chamber. Because the heating element sits close to the food and a fan circulates hot air rapidly around it, heat transfers far more efficiently than in a large conventional oven. That efficiency is exactly why the temperature and time both need to come down — running an air fryer at full oven settings will typically overcook or burn food well before the packet's stated time is up.

Frequently Asked Questions (FAQs)

It's a tool that converts standard conventional oven cooking instructions, temperature and time, into the correct settings for an air fryer, since most food packaging only lists oven instructions.

As a general rule, reduce the oven temperature by 40°C for an air fryer. For example, 200°C in a conventional oven becomes 160°C in an air fryer. This calculator applies that conversion automatically for any temperature.

Air fryers are compact, high-speed convection ovens. Their small cooking chamber and fast-circulating hot air transfer heat far more efficiently than a full-sized oven, so food cooks noticeably faster and needs roughly 20% less time.

This calculator uses a general 20% reduction rule that works well for most everyday foods like frozen snacks, chicken, vegetables, and baked goods. Delicate items or very large cuts of food may need small manual adjustments, so check food is cooked through before eating.

Many air fryers cook well without preheating, but a short 2-3 minute preheat at the converted temperature can help achieve more even, consistent results, especially for foods that benefit from a crisp exterior.

Yes. Each temperature option already shows the equivalent fan oven value alongside the standard oven value, so you can pick whichever one matches your packaging instructions.
