Shake or flip halfway for even browning.

A 190°C oven recipe goes in the air fryer at 175°C (345°F), with the cooking time cut by 20%. So 190°C for 25 minutes becomes 175°C for 20 minutes. In Fahrenheit, 190°C is 374°F, or gas mark 5.

The formula

  1. Air fryer temperature = oven temperature − 25°F (or − 15°C), rounded to the nearest 5°.
  2. Air fryer time = oven time × 0.8 (20% less). By food type: Most recipes × 0.8, Thin & crispy × 0.75, Vegetables × 0.75, Thick meat & roasts × 0.85, Cakes & bakes × 0.85, Frozen food × 0.8.
  3. Check at = oven time × 0.75, rounded down.

Worked example: 400°F − 25°F = 375°F · 25 min × 0.8 = 20 min · check at 18 min

Results above 400°F (200°C) get a warning, because many basket air fryers stop there. Method version 1.1. Why these numbers: methodology.

Every row below is 190°C in the oven and 175°C in the air fryer. The time cut depends on the food: thin, crispy foods finish sooner, while thick meat and cakes need closer to their full time.

190°C in Fahrenheit, fan and gas mark

190°C expressed in other units and oven types
Conventional oven190°C = 374°F (recipes use 375°F)
Fan / convection oven350°F / 175°C fan
Gas ovenGas mark 5
Air fryer175°C / 345°F

The fan figure uses the same rule as the air fryer, because both cook with moving air. If a recipe already gives a fan or convection temperature, use it in the air fryer unchanged and only shorten the time by about 10%: see convection oven to air fryer or fan oven to air fryer.

Why 190°C becomes 175°C

An air fryer is a small convection oven with a powerful fan. Moving air carries heat into food faster than the still air of a regular oven, so the same browning happens at a lower setting:190°C − 15°C = 175°C. The result is rounded to the nearest 5 degrees to match air fryer dials.

Accuracy and limitations

The arithmetic is exact: the same function produces the calculator result, every chart on this site and the printable chart. The cooking result is an estimate, because the formula cannot see your appliance or your food.

  • Appliances vary. Wattage, basket size and how close the element sits to the food change cooking speed. That’s why every result includes a “check at” time.
  • Load matters. A full or stacked basket cooks more slowly than a single layer.
  • Temperature limits. Many basket air fryers stop at 400°F (200°C). Converted settings above that are flagged.
  • Poor fits for any formula: wet batters, delicate cakes, low-and-slow recipes and roasts over an hour. Use a thermometer and expect to adjust.
  • Food safety comes from internal temperature, not time. Check meat, poultry, seafood and leftovers against the USDA safe minimum temperatures.

Frequently asked questions

What is 190°C in an air fryer?

A recipe written for a 190°C conventional oven converts to 175°C (about 345°F) in the air fryer, with the cooking time multiplied by 0.8. If the recipe already gives an air fryer temperature, keep it as it is.

How long is 20 minutes at 190°C in an air fryer?

About 16 minutes at 175°C. Start checking at 15 minutes; thin, crispy foods may be done sooner and thick cuts may need the full time.

What is 190°C in Fahrenheit?

190°C is exactly 374°F. Recipes usually treat it as 375°F. On a gas oven it is about gas mark 5.

What is 190°C in a fan oven?

Lower it by 15°C to about 175°C (350°F) fan. A fan or convection oven circulates air like an air fryer, so a fan temperature goes straight into the air fryer unchanged.

What is a 190°C air fryer recipe in the oven?

Going the other way, a 190°C air fryer recipe needs about 205°C in a conventional oven, with the time multiplied by 1.25.
