Oven to Air Fryer Conversion Calculator
The oven to air fryer rule
An air fryer is a small fan oven, so food cooks faster and needs a lower setting. The reliable starting point is to drop the temperature by about 20°C and cut the time by roughly 20 percent, which is exactly what this calculator does. So a tray of something at 200°C for 30 minutes in the oven becomes about 180°C for 24 minutes in the air fryer.
Treat the result as a first checkpoint rather than a finished time: air fryers vary a lot by model and by how full the basket is, so open it a few minutes early, shake or turn the food, and go by colour and a probe rather than the clock. Convert oven dials first with the oven temperature converter.

Are these figures exact?
They are reliable guides based on standard UK values, but ingredients, ovens and appliances vary. For anything involving meat, always check it is cooked through with a thermometer rather than relying on time alone.
