Air Fryer Converter
Convert oven temperatures and cook times to air fryer settings. Includes a quick reference table for popular foods.
Air fryers cook faster and at lower temperatures than conventional ovens because they circulate hot air rapidly in a compact space. The general rule is to reduce the oven temperature by about 25 degrees F (15 degrees C) and shorten the cook time by 20%. This converter does that math for you - enter your oven recipe settings and get the air fryer equivalent. Works in both Fahrenheit and Celsius.

The Conversion Rule
| Setting | Oven | Air Fryer | Adjustment |
|---|---|---|---|
| Temperature (F) | 400F | 375F | Reduce by 25F |
| Temperature (C) | 200C | 185C | Reduce by ~15C |
| Cook time | 30 minutes | 24 minutes | Reduce by 20% |
This rule works for the vast majority of recipes. The reduced temperature compensates for the air fryer's more efficient heat transfer, and the shorter time prevents overcooking. Always check your food a few minutes early, especially the first time you convert a new recipe.
Common Food Conversion Reference
| Food | Oven Temp | Oven Time | Air Fryer Temp | Air Fryer Time |
|---|---|---|---|---|
| Chicken wings | 400F / 200C | 40-45 min | 375F / 190C | 22-26 min |
| Chicken breast | 400F / 200C | 25-30 min | 375F / 190C | 18-22 min |
| Frozen chips / fries | 425F / 220C | 20-25 min | 400F / 200C | 15-18 min |
| Salmon fillet | 400F / 200C | 15-18 min | 375F / 190C | 10-12 min |
| Roast vegetables | 425F / 220C | 30-35 min | 400F / 200C | 18-22 min |
| Pizza (frozen) | 425F / 220C | 12-15 min | 375F / 190C | 8-10 min |
| Bacon | 400F / 200C | 15-20 min | 375F / 190C | 8-10 min |
| Fish fingers / sticks | 425F / 220C | 15-18 min | 400F / 200C | 10-12 min |
| Baked potato | 400F / 200C | 45-60 min | 400F / 200C | 35-40 min |
These are starting points. Actual times depend on food thickness, whether it is fresh or frozen, and your specific air fryer model. Flip food halfway through for even browning.
Why Air Fryers Cook Differently
| Factor | Conventional Oven | Air Fryer |
|---|---|---|
| Heating method | Radiant heat from elements, natural convection | Rapid forced convection from a powerful fan |
| Cooking space | Large cavity - heat is diffuse | Compact basket - heat is concentrated |
| Preheat time | 10-15 minutes | 2-3 minutes (some skip entirely) |
| Air circulation speed | Slow or none (except convection ovens) | Very fast - creates the "frying" effect |
| Moisture removal | Moderate | High - food surfaces dry quickly, creating crispiness |
A convection oven is closer to an air fryer than a standard oven. If your recipe is already written for a convection oven, reduce the air fryer temperature by only 10-15F (5-10C) and the time by 10%.
Tips for Best Air Fryer Results
| Tip | Why |
|---|---|
| Do not overcrowd the basket | Air needs to circulate around the food - overcrowding creates steaming instead of crisping |
| Use a light spray of oil | A thin coat of oil on food surfaces helps achieve a golden, crispy finish |
| Shake or flip halfway through | Ensures even browning on all sides |
| Check food 2-3 minutes early | Air fryer models vary in power - check early until you know yours |
| Use parchment liners (with holes) | Makes cleanup easier and prevents sticking without blocking airflow |
| Pat food dry before cooking | Surface moisture prevents crisping - dry food = crispier results |
What Works (and Does Not Work) in an Air Fryer
| Works Well | Does Not Work Well |
|---|---|
| Frozen snacks (chips, nuggets, spring rolls) | Wet batters (tempura batter flies off in the fan) |
| Breaded items (breadcrumbs stay put) | Large casseroles or liquid-heavy dishes |
| Roasted vegetables | Very light foods (leafy greens blow around) |
| Chicken, fish, steak | Whole roasts (usually too large for the basket) |
| Reheating leftovers (better than microwave) | Cheese-topped dishes (cheese drips through basket) |
| Baked goods (muffins, small cakes) | Large cakes or bread loaves |
If your recipe uses Celsius but your air fryer shows Fahrenheit (or vice versa), the Temperature Converter can help with that separately. For converting ingredient weights between metric and imperial, the KG to LBS Converter handles that. All calculations run in your browser.
How the 25F / 20% Rule Was Established
The commonly cited conversion rule - reduce oven temperature by 25F (about 15C) and cook time by 20% - is published by Good Housekeeping's test kitchen, Food Network, and manufacturer guides including Ninja Kitchen and Philips. It reflects a simple fact: an air fryer is a compact, high-speed convection oven. The British Nutrition Foundation notes that forced-air convection transfers heat 25-30% more efficiently than still air, which is why the same food cooks to the same internal doneness at a lower setting.
Worked example: A recipe says "roast salmon at 400F for 18 minutes in the oven". Air fryer temperature = 400 - 25 = 375F. Air fryer time = 18 x 0.8 = 14.4, rounded to 14 minutes. Check internal temperature with a probe thermometer - salmon is done at 145F (63C) per USDA FSIS guidelines. If it is not quite there at 14 minutes, add 1-2 minutes at a time.
How Much Energy Does an Air Fryer Actually Save?
An air fryer uses roughly half the energy of a conventional oven for the same meal, according to a 2024 analysis by Uswitch using UK Ofgem electricity rates. A typical 1,500W air fryer running for 20 minutes consumes about 0.5 kWh. A 2,500W electric oven running for 35 minutes (including preheat) consumes about 1.46 kWh. At the April 2026 Ofgem price cap of 27.03p per kWh, that is a saving of about 26p per meal - roughly GBP 95 per year for a household that cooks five times a week.
| Appliance | Typical Wattage | Run Time | Energy Used | Cost (27.03p/kWh) |
|---|---|---|---|---|
| Electric oven | 2,500 W | 35 min (inc. preheat) | 1.46 kWh | ~39p |
| Gas oven | n/a (6.04p/kWh) | 35 min | ~1.5 kWh | ~9p |
| Air fryer (1,500W) | 1,500 W | 20 min | 0.50 kWh | ~14p |
| Microwave (900W) | 900 W | 6 min | 0.09 kWh | ~2p |
The savings are largest versus an electric oven. If you have a gas oven, the per-meal energy cost is already low, so the air fryer wins mainly on speed and texture rather than pence saved.
Does Air Frying Affect Nutrition or Food Safety?
Air frying produces less acrylamide than deep frying, according to a 2024 study in the journal Food Chemistry that measured potato products cooked at matched doneness. Acrylamide is a compound the UK Food Standards Agency links to cancer risk at high exposure. Because air fryers use a fraction of the oil of deep frying, typical calorie counts drop by 70-80% for foods like chips and breaded chicken.
Food safety still follows the same internal temperature rules as any other cooking method. Use a probe thermometer and aim for these USDA FSIS-recommended minimum internal temperatures:
| Food | Minimum Safe Internal Temp |
|---|---|
| Poultry (chicken, turkey) | 165F / 74C |
| Ground meat (beef, pork, lamb) | 160F / 71C |
| Steaks, chops, roasts (beef, pork, lamb) | 145F / 63C with a 3-minute rest |
| Fish and shellfish | 145F / 63C |
| Leftovers and casseroles | 165F / 74C |
| Eggs (cooked dishes) | 160F / 71C |
The NHS and FSA advise that browning alone is not a reliable indicator of doneness - check with a thermometer, particularly for poultry and ground meat.
Common Air Fryer Mistakes
| Mistake | What Goes Wrong | Fix |
|---|---|---|
| Cooking at the full oven temperature | Food burns on the outside while still raw inside | Always drop the temperature by 25F (15C) |
| Ignoring cook time reduction | Overcooked, dry results | Reduce time by 20% and check early |
| Piling food in layers | Steaming, not crisping - wet bottoms | Cook in a single layer, batch if needed |
| Using aerosol oil sprays | Damages the non-stick coating over time | Use a refillable pump mister with plain oil |
| Skipping the flip | Pale on one side, dark on the other | Shake or turn at the halfway point |
| Washing the basket in the sink | Residual soap ruins the next meal | Rinse thoroughly or use the dishwasher safe parts |
Adjusting for Your Specific Model
Air fryers vary in wattage (usually 1,200-1,800W) and basket shape, which affects cooking speed. A higher-wattage model (1,800W Ninja Foodi, for example) cooks 10-15% faster than a 1,200W compact unit. The first time you convert a familiar recipe, check the food at 70% of the suggested air fryer time and note the actual time needed. Over a few weeks you will learn the "offset" for your machine.
Basket size matters too. A 4-quart basket fits one to two portions; a 6-quart or larger can handle a family meal in one batch. For a dual-zone model, treat each drawer independently - they do not share air flow. For ingredient conversions between recipes written in different units, the Cooking Unit Converter is useful.
Air Fryer vs Convection Oven vs Conventional Oven
An air fryer is effectively a miniature convection oven. The distinction matters for conversion maths: a recipe written for a convection oven has already been adjusted downward from its conventional-oven version. Applying the full 25F / 20% rule on top of that tends to undercook.
| Source Recipe | Target | Temperature Change | Time Change |
|---|---|---|---|
| Conventional oven | Air fryer | Reduce by 25F (15C) | Reduce by 20% |
| Convection oven | Air fryer | Reduce by 10-15F (5-8C) | Reduce by 10% |
| Air fryer | Conventional oven | Increase by 25F (15C) | Increase by 25% |
| Air fryer | Convection oven | Match the temperature | Add 10-15% |
If the recipe does not specify, assume conventional oven - most home recipe sites publish for a standard oven by default. For baking specifically, convection and air fryer temperatures should drop an additional 10-15F vs roasting, because the constant airflow browns pastry faster than the inside sets.

Frequently Asked Questions
How do you convert oven temperature to air fryer?
The general rule is to reduce the oven temperature by 25 degrees Fahrenheit (about 15 degrees Celsius) when using an air fryer. Air fryers circulate hot air more efficiently than conventional ovens, so they cook at a lower temperature with the same or better results.
How much less time does an air fryer need compared to an oven?
Air fryer cook times are typically about 20% shorter than oven cook times. For example, if a recipe calls for 30 minutes in the oven, try around 24 minutes in the air fryer. Check food a few minutes early until you learn how your specific model performs.
Do I need to preheat my air fryer?
Most air fryers reach their target temperature much faster than ovens, usually within 2-3 minutes. Some models recommend a brief preheat for the best results, while smaller units often skip preheating entirely. Check your manual for specific guidance.
Can I use any oven recipe in an air fryer?
Most baked and roasted recipes translate well. Foods with wet batters or very loose coatings may not work as well because the high-speed air circulation can blow the batter around. Dishes that require a lot of liquid, like casseroles, are also better suited for a conventional oven.
Why does the air fryer cook faster?
Air fryers use a powerful fan to circulate hot air rapidly around the food in a small, enclosed space. This concentrated airflow transfers heat more efficiently than the still air inside a standard oven, resulting in shorter cook times and crispier surfaces.
