Formula
kilograms = value x unit factor (1 lb = 0.45359237 kg exactly, 1 oz = 1/16 lb, 1 st = 14 lb)Understanding Weight Conversion
Mass is measured in kilograms in the metric system, while the United States uses pounds and ounces and the UK often uses stones for body weight. The avoirdupois pound has been defined as exactly 0.45359237 kilograms since 1959, so conversions are exact. Strictly, weight is a force and mass is an amount of matter, but in everyday use both words mean the same thing on a scale at the surface of the Earth.
Tips and Best Practices
- 1To convert kilograms to pounds, multiply by 2.20462; to convert pounds to kilograms, multiply by 0.45359.
- 2A stone is 14 pounds, so body weight in stones and pounds needs a division by 14 and a remainder.
- 3Jewelry uses carats (200 mg) for gemstones; do not confuse them with karats, which measure gold purity.
Real-World Example
A 70 kg person weighs 70 x 2.20462 = 154.32 lb, which is 11 stone and 0.3 lb. A 500 g bag of flour is 17.64 oz.
Common Mistakes to Avoid
- Confusing the short ton (2,000 lb, US) with the long ton (2,240 lb, UK) and the metric tonne (1,000 kg).
- Using troy ounces for gold with the regular avoirdupois ounce factor; troy ounces are heavier.
- Reading a stone value like 11.5 st as 11 st 5 lb; it is 11 st 7 lb.
