About the Pound

Facts & Uses

  • Primary unit of mass in US customary and imperial systems; defined as exactly 0.45359237 kilograms by the 1959 International Yard and Pound Agreement.
  • Standard for body weight (US healthcare), retail food packaging, postal rates, and freight in the United States and parts of the Commonwealth.
  • Used in sports (boxing/MMA weight classes, weightlifting plates), firearms (bullet weight in grains, where 7000 grains = 1 lb), and cooking (US recipes).
  • Subdivisions: ounce (1 lb = 16 oz), grain (1 lb = 7000 gr); multiples: stone (UK, 14 lb), hundredweight, short ton (2000 lb).

Curiosities

  • The symbol "lb" comes from the Latin libra pondo ("a pound by weight"), the same root as the British currency pound sign £.
  • Historically, dozens of regional pounds existed across Europe (Tower pound, merchant's pound, troy pound); the 1959 Agreement standardized the avoirdupois pound for English-speaking nations.
  • The troy pound (used for precious metals) is different — 1 troy lb = 12 troy oz = 373.2417216 g, lighter than the avoirdupois pound.
  • 1 lb = exactly 453.59237 g — one of the few imperial-to-metric conversions defined to perfect precision.
