About AirFryConverter.com
Written by Kate Farrell | Last updated: March 2026
I'm Kate. I'm a UX designer from Bristol, and I built this site because I got frustrated — which, honestly, is how most side projects start.
My partner Dan gave me a Ninja AF100 for Christmas 2023. It sat on the counter for two weeks while I convinced myself I didn't need another appliance. Then I made frozen chips with it and promptly forgot to reduce the cooking time. They were somewhere between crispy and carbonised. Not my best work.
After that I started Googling "oven to air fryer conversion" properly, expecting a quick answer. What I found instead was the same two sentences recycled across dozens of sites — reduce the temperature by 25°F, reduce the time by 20% — usually buried inside a 2,000-word post that opened with someone's grandmother's recipe and took four scrolls to get to anything useful. A few sites had calculators, but most were broken, or didn't handle Celsius, or just felt like they'd been thrown together in an afternoon and never tested.
So I built one myself. I know enough JavaScript from my day job to put something basic together, and I spent a weekend in mid-2025 making a calculator that actually worked the way I wanted it to. I shared it in a Facebook group for air fryer owners expecting maybe a handful of responses.
I got flooded.
I spent the rest of 2025 building it out properly. AirFryConverter.com launched in January 2026.
What this site is — and isn't
This is a conversion tool, not a recipe blog. I'm not going to describe the "rustic charm" of a Sunday roast or tell you that air fryer Brussels sprouts will change your life. They won't change your life. They are, however, genuinely better than the oven version, and I'll tell you exactly what temperature and time to use.
The guides on this site come from actual testing — on my Ninja Dual Zone AF400, with input from other model owners, and cross-referenced against USDA food safety guidelines where temperatures matter. I'll always tell you when something varies by machine, because it does. Air fryers aren't all the same, and anyone who tells you there's one universal answer for everything hasn't cooked enough to know better.
I'm not a chef or a food scientist. When I cite food safety temperatures, those come from the USDA — not from me personally deciding that 160°F seems about right. I'm clear about that distinction throughout the site.
Why I think this site is different
Most air fryer content is written by recipe bloggers who added an air fryer to their existing setup and need to produce content at volume. There's nothing wrong with that, but it means a lot of advice is untested, recycled, and written for SEO rather than for the person actually standing at their counter at 6pm trying to figure out if their chicken is cooked.
My background is UX — I spend my working days thinking about how people actually use things versus how designers assume they'll use them. That's the lens I bring here. I want the answer to be in the first two sentences. I want the chart to load before the scroll. I want the calculator to work on a phone with one hand.
That's it, really.
