How weight conversion works
Mass uses a base unit of kilograms. All units convert to kg first, then to the target. Key factors: 1 lb = 0.45359237 kg, 1 oz = 0.028349523125 kg, 1 g = 0.001 kg.
Common weight conversions and uses
Weight conversion is essential for health tracking (kg vs lb for body weight), cooking (grams vs ounces for ingredients), and shipping (package weight in different units). The metric system uses kilograms and grams; the US customary system uses pounds and ounces. This converter handles both accurately. Use it with our BMI calculator (which accepts kg and cm), calorie calculator, or any tool that needs weight in a specific unit.
For volume conversions (liters, gallons, cups), use the volume converter. For length, use the length converter. For a general tool that covers multiple categories, use the unit converter. All conversions run locally in your browser with no data stored.
