Pounds: A Unit of WeightDefinition of the PoundA pound is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to 0.45359237 kilograms, or 16 ounces, or 7000 grains. One pound can also be written as lb or lbs. History of the PoundThe pound was originally defined in ancient Rome as the mass of a bronze bar called a libra, which was divided into 12 ounces. The libra was later adopted by various regions and countries in Europe, such as England, France and Germany, with different values and subdivisions. The pound as we know it today is based on the avoirdupois system, which was developed in the 13th century in France and England. The avoirdupois pound was standardized in 1959 by an international agreement among the United States, Canada, Australia, New Zealand and South Africa as exactly 0.45359237 kilograms. The pound, as well as other units of weight, such as the ounce and the ton, were introduced in the 19th century as part of the imperial system of measurement that aimed to unify the units used in the British Empire. The pound was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.
