About these units

Pound (lb)

US & ImperialCurrent unit

Exactly 0.45359237 kg, divided into 16 ounces. The standard unit of weight in the US and common in the UK.

Why is pound abbreviated lb? The answer is Roman. The English word comes from the Latin libra pondo, roughly the weight measured in libra, and the symbol keeps the first word. The Roman libra was divided into 12 unciae. The avoirdupois pound of 16 ounces came into general use around 1300 and was initially equal to 6,992 troy grains; under Elizabeth I it was redefined as 7,000 grains. The UK's Weights and Measures Act 1878 set the imperial standard pound as a platinum cylinder, and the troy pound was abolished for trade the following year.

Today the pound is defined from the kilogram. The International Yard and Pound Agreement of 1959 fixed it at exactly 0.45359237 kg, and the UK's Weights and Measures Act 1963 wrote the same figure into law. Pounds remain the everyday unit for body weight, groceries and shipping in the United States and are widely used in the UK. The word also survives in odd places: a six-pounder cannon was named for the weight of its shot, not its own.

1 pound = 0.45359237 kilograms (exactly).

Quarter (UK) (qr)

Imperial (British)Historical unit (no longer in standard use)

28 pounds (12.7 kg), a quarter of a long hundredweight. A traditional British unit of weight.

Taking one fourth of a larger unit, as the name suggests, produced several quarters in British measure. The mass version is 28 pounds, a quarter of the 112 pound long hundredweight and two stone, which is roughly 12.7 kilograms. The Units of Measurement Regulations 1994 define it as 28 pounds.

A second quarter measured dry goods. Under the Weights and Measures Act 1824 a quarter of grain was eight bushels, or 64 imperial gallons, about 290.95 liters, a size known as the quarter of London since the Latin quarterium Londoniense of Magna Carta. The 1985 Act dropped it as a volume unit. The weight quarter lingers on old anvils and bells stamped in hundredweight, quarters and pounds: an anvil marked 1.1.8, for example, weighs 148 pounds. Four of them make a hundredweight, and eighty make a long ton.

1 quarter (UK) = 12.70058636 kilograms (exactly).
