How do I convert an oven recipe to air fryer?
Subtract 25°F (15°C) from the oven temperature and reduce cooking time by 20–25%. An air fryer circulates hot air faster than an oven. Example: 400°F oven → 375°F air fryer. Use our Air Fryer to Oven Calculator for exact conversions with food-specific tips.
What is Gas Mark 4 in Fahrenheit and Celsius?
Gas Mark 4 = 350°F / 177°C. Each Gas Mark adds ~25°F. Gas Mark 6 = 400°F (200°C). Gas Mark 7 = 425°F (220°C).
All four temperature scales side by side. The Air Fryer column is 25°F lower than the conventional oven column — the standard conversion for most recipes.
