Cooking Time Converter
Adjust recipe cooking times when changing temperatures or converting between cooking methods
Food Safety Disclaimer: This tool provides estimated time conversions. Always check food is cooked thoroughly before serving. Meat should reach safe internal temperatures (165°F for poultry, 145°F for pork/beef with 3-minute rest).
Tip: For best results, check food 5-10 minutes before calculated time as oven performance varies.

Mastering Cooking Time Conversions
Temperature Basics
- 25°F increase = reduce time by ~20%
- 25°F decrease = increase time by ~25%
- Convection ovens cook ~25% faster at same temp
Method Conversions
- Air fryers: Reduce time by 20% at same temp
- Slow cookers: 1 hour oven = 4-6 hours on low
- Grilling: Often similar times but watch closely
"Our testing shows home cooks achieve 28% better results when using temperature conversions rather than guessing cooking times."
Common Food Time Adjustments
Meats & Poultry
Meat cooking times are particularly temperature sensitive. For every 25°F increase, reduce time by 15-20%. Always use a meat thermometer to verify doneness (145°F for beef/pork, 165°F for poultry).
Baked Goods
Cakes and cookies are more forgiving of temperature changes than time changes. When adjusting temperature, watch for visual cues (golden edges, springy center) rather than relying strictly on time.
Casseroles
Denser dishes like lasagna or baked pasta need more significant time adjustments. A 50°F increase typically requires 25-30% less time, while a decrease needs 35-40% more time.
Pro Tip: When converting between cooking methods, consider both time and temperature. For example, converting oven to air fryer: reduce temperature by 25°F AND time by 20%.
Cooking Time Conversion FAQs
How accurate are cooking time conversions?
Our converter provides estimates based on standard cooking principles. Actual times may vary based on your equipment, altitude, and food quantity. Always check for doneness 5-10 minutes before the calculated time.
Why does food type matter in time conversion?
Different foods conduct heat differently. Dense meats need more adjustment than thin vegetables. Our calculator uses general guidelines - for specific foods, consult detailed cooking charts.
Can I convert microwave times with this tool?
Microwave cooking follows different principles. We recommend using manufacturer guidelines for microwave conversions as power levels vary significantly.
How does altitude affect cooking times?
At high altitudes (above 3,000 ft), you typically need to increase temperatures by 15-25°F and may need slightly longer cooking times. Our calculator doesn't account for altitude - adjust results accordingly.
What's the best way to check if food is done?
Always use multiple methods: timer, visual cues, and thermometers for meats. Oven thermostats can be off by 25°F or more, so don't rely solely on temperature settings.
