About Weight and Mass
Weight and mass are closely related but technically different concepts. Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass. In everyday use, the terms are often interchangeable. The metric system uses grams and kilograms, while the imperial system uses ounces and pounds.
Key conversions include: 1 kilogram = 2.20462 pounds, 1 pound = 16 ounces, 1 stone = 14 pounds, and 1 metric tonne = 1,000 kilograms. The US short ton equals 2,000 pounds, while the imperial long ton equals 2,240 pounds. These conversions are essential for cooking, shipping, fitness tracking, and scientific work.
