Air fryer temperature conversion — Celsius
Metric-first: enter your oven recipe in °C and get an air-fryer temperature rounded to a real dial step. Already set to Celsius below.

How we convert this
A starting point — air fryers run hot and every model differs. Check doneness by sight, and for meat use a thermometer and the USDA safe internal temperature.
Converting oven temperatures to air fryer in Celsius
If your oven and air fryer are labelled in Celsius, the conversion works exactly as it does in Fahrenheit — the temperature comes down and the time comes down — but there’s one detail worth getting right. The most common rule, “subtract 25°F,” is defined in Fahrenheit, so the honest way to apply it in metric is to convert, subtract, and convert back, rather than guessing a round Celsius number.
Do the steps in the right order
Take a recipe at 200°C. Convert to Fahrenheit (392°F), subtract 25°F (367°F), then convert back — about 186°C, which rounds to 185°C on a dial. Reduce the time by roughly 20% (30 minutes → 24) and start checking near 70% (about 21 minutes). That’s the example loaded in the converter above. If you’d rather use the proportional −20% rule, switch the temperature rule in the tool; it lands a touch lower, around 180°C.
Why the nearest 5°
Air-fryer dials and digital pads step in fives and tens, not single degrees. An exact 186°C isn’t a setting you can choose, so the calculator rounds to the nearest 5° — a number you can actually dial in. It’s a deliberately small, clearly-labelled rounding; a degree either way makes no practical difference next to how much models vary.
| Oven (°C) | Air fryer (°C) |
|---|---|
| 150°C | 135°C |
| 160°C | 150°C |
| 170°C | 160°C |
| 180°C | 165°C |
| 190°C | 175°C |
| 200°C | 185°C |
| 220°C | 205°C |
Cook times don’t depend on the unit — cut about a fifth either way. For a printable version in both °C and °F, grab the conversion chart.
Celsius conversion questions
What is 200°C in an air fryer?
About 180–185°C. Applying the standard −25°F rule to 200°C (392°F → 367°F → ~186°C) and rounding to a real dial gives roughly 185°C; the proportional −20% rule lands near 180°C. Cut the time by about a fifth and start checking early.
What is 180°C in an air fryer?
Around 160–165°C. 180°C is 356°F; minus 25°F is 331°F, which rounds to about 165°C on a dial. Many recipes simply use 160°C as a round metric equivalent. Either is a sensible starting point — check doneness to be sure.
Why does the tool round Celsius to the nearest 5 degrees?
Because air-fryer dials move in 5° or 10° steps, an exact figure like 186°C isn’t selectable. Rounding to the nearest 5° gives you a number you can actually set, which is why 400°F shows as ~190°C rather than 191°C. The rounding is noted in the tool so the small difference isn’t confusing.
Do I convert Fahrenheit to Celsius before or after subtracting 25°F?
After. The −25°F rule is defined in Fahrenheit, so the tool applies it first and then converts to Celsius — that keeps the °F and °C answers consistent. Doing it in the wrong order introduces a small but avoidable error.
Are UK, Australian and European air fryers different?
The math is identical — only the dial units change. Most metric-market air fryers are labelled in Celsius, so this page and the °C toggle give you numbers you can set directly. Gas Mark ovens convert to Celsius first, then follow the same rule.
