I keep a Galanz Retro 700W microwave in the office — and I'm constantly doing this mental math for whatever I'm reheating. Made this so I'd stop guessing.

Formula: new time = original time × (original watts ÷ new watts). Works well for reheating. For cooking proteins or doughs, lower wattage changes texture even at equivalent energy — results may vary.
