About AirFryerMath
AirFryerMath is a free, independent tool that converts oven recipes into air-fryer settings — and back — with per-food times and honestly-sourced safe temperatures. It’s built to give you the number fast, on your phone, in the middle of cooking.
Why it exists
Almost every recipe is written for a conventional oven, but a lot of us now reach for the air fryer first. The conversion isn’t complicated — lower the temperature, shorten the time — yet doing the arithmetic mid-recipe with greasy hands is annoying, and the “rules” you find online quietly disagree with each other. AirFryerMath does the maths for you, shows its working, and is honest about the fact that air-fryer conversion is a well-established rule of thumb, not exact science.
How it’s different
- A live two-way converter — edit the oven side or the air-fryer side and the other updates instantly, so it works in either direction.
- Two temperature conventions — the fixed −25°F rule and the proportional −20% rule, side by side, because publishers genuinely disagree.
- Per-food pages with cited times — wings, fries, bacon, salmon and chicken breast, each with tested settings and the USDA safe internal temperature spelled out.
- A free printable chart — no email wall, no sign-up. Print it or save the PDF.
- Honesty first — every result says it’s a starting point and reminds you to check doneness; safe temperatures are cited to the USDA, never invented.
Our honesty promise
Food-safety numbers matter, so we never guess them. Every safe internal temperature on this site is the USDA/FSIS figure, cited toFoodSafety.gov. Per-food cook times are common starting points drawn from tested recipes and shown as ranges, not false-precision single numbers. And we always tell you the same true thing: a conversion gets you close, but a thermometer and your own eyes decide when food is done.
Who’s behind it
AirFryerMath is a small, independent project — no venture backing, no data harvesting, no newsletter you have to escape. It’s a sibling ofLoafMath, a set of free baking calculators, and shares its plain philosophy: make one useful thing, make it fast, and don’t get in the way. It isn’t affiliated with any appliance manufacturer; brand names like Ninja are used only to describe the air fryer you might own.
