Enter your oven temperature and cooking time into the Air Fryer Conversion Calculator and get the recommended air fryer temperature and adjusted cook time back. Choose between Celsius and Fahrenheit, and the calculator applies the standard 25°F (15°C) temperature reduction and 20% time reduction used in air fryer cooking.

Yes — air fryers typically cook food around 20% faster than a conventional oven. This is because the compact cooking chamber and powerful circulating fan concentrate heat directly around the food, reducing the time needed to reach the same internal temperature.
The standard rule is to reduce your oven temperature by 25°F (about 15°C) when using an air fryer. So if your recipe calls for 400°F in the oven, set your air fryer to 375°F. If you're using a fan/convection oven as your starting point, a smaller reduction of around 10°F (5°C) is more appropriate.
Reduce the original oven cooking time by approximately 20% when air frying. For example, a dish that takes 30 minutes in the oven should take around 24 minutes in an air fryer. Always check food for doneness a few minutes early, especially the first time you cook a new recipe.
375°F in a conventional oven converts to approximately 350°F in an air fryer. The 25°F reduction accounts for the air fryer's more efficient heat circulation, which cooks food just as thoroughly at a lower set temperature.
For most everyday cooking — roasting vegetables, cooking chicken, reheating leftovers, or baking small portions — yes. Air fryers are not ideal for large roasts, big batches, or dishes that require a moist baking environment like bread or cheesecake, where a conventional oven performs better.
Use the two standard adjustments: reduce the temperature by 25°F (15°C) and reduce the cooking time by 20%. Keep an eye on your food during the first attempt with a new recipe, as results can vary slightly depending on the air fryer model and the size of the food being cooked.
Use this calculator any time you have a recipe written for a conventional oven and want to adapt it for your air fryer. It's especially useful when cooking packaged foods that list oven instructions, or when scaling a new recipe you haven't tried in the air fryer before.
Yes. Fan or convection ovens already circulate hot air and run about 15–20°C hotter than conventional ovens at the same setting. If your recipe is written for a fan oven, a smaller temperature reduction is needed when converting to air fryer settings, which this calculator accounts for.
