When to use this calculator

  • Converting body weight between kilograms and pounds for fitness tracking
  • Translating recipe weights between ounces and grams for cooking and baking
  • Calculating shipping weights across metric and imperial systems
  • Converting bulk material weights between metric tonnes and pounds
  • Helping students learn metric-imperial mass conversion relationships

How the calculation works

All weight conversions use a direct multiplier from the base unit (grams). Each unit has a fixed conversion factor: 1 kilogram = 1000 grams, 1 pound = 453.592 grams, 1 ounce = 28.3495 grams, 1 stone = 6350.29 grams. To convert, the calculator first translates your "from" value to grams by multiplying by its factor, then translates grams to the "to" unit by dividing by the target factor. For example, 70 kilograms to pounds: 70 × 1000 = 70,000 grams, then 70,000 ÷ 453.592 ≈ 154.32 pounds.

Is mass the same as weight?▼
Strictly, mass is the amount of matter in an object (measured in grams) while weight is the force gravity exerts on that mass. In everyday use the terms are interchangeable, and this converter handles the common mass units used for body weight, cooking, and shipping.
