Cooking Time Converter: Oven, Air Fryer, Microwave, Slow Cooker

Stop guessing. Our Cooking Time Converter adjusts time and temp for oven, air fryer, microwave, slow cooker — with thickness, doneness, and altitude.

Why Conversion Matters

Each method cooks differently:

  • Air Fryer: 25% faster, 25°F lower
  • Microwave: 4× faster, but uneven
  • Slow Cooker: 6–8 hr low, 3–4 hr high
  • Altitude: Water boils at lower temp

How to Use

  1. Select original & target method
  2. Enter temp & time
  3. Add thickness, doneness, altitude
  4. Get adjusted time + temp

Oven to Air Fryer

  • Temp: Subtract 25°F
  • Time: Reduce by 20–25%
  • Shake/flip halfway

Microwave Cooking

  • 1000W: 1 min oven = ~15 sec microwave
  • Stir halfway
  • Let stand 1–2 min

Slow Cooker

  • 1 hr oven = 6–8 hr low, 3–4 hr high
  • Add ½ cup liquid
  • Don’t lift lid

Meat Doneness

  • Rare: 125°F
  • Medium: 145°F
  • Well: 160°F
  • Rest 3–5 min

Thickness Rule

Time ∝ thickness² (for conduction)

  • 1" steak: 4 min/side
  • 2" roast: 16 min/lb

High Altitude (>3000 ft)

  • Boiling: +1 min per 1000 ft
  • Baking: +15–25°F, +5–25% time
  • Reduce leavening & sugar

Pro Tips

  • Use thermometer
  • Preheat air fryer
  • Cover microwave food
  • Layer slow cooker
