Air Fryer Calculator
Turn any oven recipe into the right air fryer temperature and time. Enter your oven settings and the numbers update as you type.
The temperature your recipe lists for a conventional oven.
💡Air fryers circulate hot air, so food cooks faster and crisps more than in an oven. Enter your oven settings to get started.
Results are a starting point. Air fryer models vary, so always check food is fully cooked before serving. ♨️
Air fryers are basically compact convection ovens. The fan moves hot air right around the food, so it cooks faster and browns more aggressively than a still oven at the same setting. That is why following an oven recipe exactly often leaves you with edges that are too dark and a middle that is not done. This calculator does the small bit of maths for you, but here is exactly how it works so you can adjust with confidence.
How the air fryer conversion works
There are two simple adjustments behind every result above:
- Lower the temperature by about 25°F (15°C). The circulating air delivers heat more efficiently, so a slightly lower setting gives you the same browning without burning.
- Cut the time by roughly 20%. Faster heat transfer means food is ready sooner, so start checking well before the original recipe time.
A few foods get a small tweak: fries and frozen snacks crisp quickest, while delicate bakes and bread do better with a gentler reduction. Pick a food type above and the calculator adjusts for you. Whatever the number says, the golden rule is the same: check early, since every air fryer runs a little differently.
Oven to air fryer conversion chart
Prefer to eyeball it? This quick reference covers the most common baking temperatures, using the standard 25°F (15°C) reduction.
| Oven °F | Air fryer °F | Oven °C | Air fryer °C |
|---|---|---|---|
| 325°F | 300°F | 160°C | 145°C |
| 350°F | 325°F | 175°C | 160°C |
| 375°F | 350°F | 190°C | 175°C |
| 400°F | 375°F | 200°C | 185°C |
| 425°F | 400°F | 220°C | 205°C |
| 450°F | 425°F | 230°C | 215°C |
For time, multiply the oven minutes by about 0.8: a 20-minute bake becomes roughly 16 minutes, 30 minutes becomes about 24, and 45 minutes becomes around 36.
Tips for converting oven recipes
- Preheat if your model needs it. A 3-minute preheat helps things cook evenly from the first minute.
- Do not overcrowd the basket. Air needs room to move, so cook in a single layer for even results.
- Shake or flip halfway. It keeps colour even, especially for smaller pieces and fries.
- Use a thermometer for meat. Times are a guide; internal temperature tells you when it is truly done.
- Tent delicate bakes with foil if the top is colouring faster than the centre is cooking.
Frequently asked questions
How do you convert an oven recipe to an air fryer?
Lower the oven temperature by about 25°F (15°C) and reduce the cooking time by roughly 20%, then check doneness a few minutes early. The calculator above does both steps for you.
Do air fryers cook faster than ovens?
Yes. Because a fan circulates the hot air, food cooks more quickly and evenly, usually around 20% faster than the same recipe in a conventional oven.
Why do you lower the temperature?
The moving air transfers heat more efficiently and concentrates it in a small space, so the same oven temperature can brown or burn the outside before the inside is cooked.
Do I need to preheat the air fryer?
Many models benefit from a short preheat of about 3 minutes for even cooking, though some newer ones do not require it. Check your manual.
Is the calculator accurate for every food?
It gives a reliable starting point. Exact times still depend on your air fryer model and how thick the food is, so always confirm doneness before serving.
