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.

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.

A starting point, in any unit. Rounded or not, treat the number as a place to begin and check doneness. For meat, use a thermometer and the USDA/FSIS safe minimum internal temperatures: poultry 74°C (165°F), ground meats 71°C (160°F), beef/pork/lamb 63°C (145°F) with a rest, fish 63°C (145°F).

Questions cooks ask

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.
