Weight and mass conversions matter for cooking, shipping, fitness, science, and international trade. Although 'weight' and 'mass' are technically different concepts in physics, in everyday use the terms are interchangeable and the conversions are identical.
Understanding Kilograms and Grams
The kilogram is the SI base unit of mass and the reference point for the entire metric system. Pounds and ounces dominate in the United States, while stones remain common for body weight in the UK and Ireland. Metric tons (1,000 kg) and US tons (2,000 lb) appear in freight, agriculture, and industry — and because they differ by about 10%, confusing them is a frequent and costly mistake.
How accurate is this conversion?
The pound is defined as exactly 0.45359237 kilograms, a definition adopted internationally in 1959. This means kilogram-to-pound conversions are exact, not approximate, so you can rely on the figures in the table below for any purpose, from postage to laboratory work.
All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
