Rough estimate for solid cooked leftovers only. Microwave wattage, portion size and starting temperature are not modeled. Check early and verify 165°F (74°C) inside; use the food-specific reheating guide for a better starting point.
Microwaves have no temperature setting, so use 350°F (175°C) as a default air-fryer reheat temperature.
Air-fryer reheating takes longer than a microwave but restores crispness microwaving destroys.
Best for fries, pizza, fried chicken, and pastries — not for soups, sauces, or steaming.
Use only reheatable solid leftovers; this is not a conversion for raw food, soups or sauces. Verify leftovers reach 165°F (74°C).
The 2.5–3 multiplier is an editorial heuristic. Microwave wattage, portion mass, starting temperature and appliance performance are not modeled. Prefer the food-specific reheating guide.
How the conversion works
Set the air fryer to 350°F (175°C) and expect roughly 3× the microwave minutes.

Example calculation
A 3-minute microwave reheat becomes 350°F / 175°C for 8–9 min. The tool keeps the temperature fixed because microwaves do not provide an oven-style temperature setting.
