Why Weight & Wattage Matter
Most packaging assumes a 1000W microwave. If yours is 700W, you need about 40% more time. If it's 1200W, you need 20% less time. Our calculator adjusts this automatically to save your dinner.
The Science Behind It
Microwave energy is absorbed unevenly by frozen food. Thicker cuts (like chicken breasts) need longer per pound than thin cuts (like fish fillets). Ground meat defrosts fastest because the increased surface area allows more even penetration.
