Officially the pound is the name for at least three different units of mass:
There also exists an unofficial metric pound.
While most standards bodies define the pound as a unit of mass, most people in everyday usage use the pound as a unit of weight.
The Latin word libra describes a Roman unit of weight similar to a pound, and the abbreviation "lb" for the unit of weight and the sign £ (a crossed-out L) for the currency derived from this. The word "pound" itself comes from the Latin pendere, to weigh.
In the Imperial system (often referred to as the pound-inch system, or the British system in the United States) there are two basic pounds defined, and also an obsolete definition of one variant of the pound:
The pound (avoirdupois) or international pound, abbreviation "lb" or sometimes # in the United States, is the mass unit defined as exactly 0.45359237 kilograms (or 453.59237 grams). This definition has been in effect since 1959 in the United States. [1] It is part of the avoirdupois system of mass units.
In the United States, the pound has been officially defined as a unit of mass and defined in relation to the kilogram since 1893, but its value in relation to the kilogram was altered slightly in 1894, and again to its current value in 1959 (which only differs from the 1894 definition by approximately one part in 10 million).
There are 16 ounces in a pound (avoirdupois). The pound is equal to exactly 7000 grains, where a grain is exactly 0.06479891 gram. The legal definition of the pound in the United Kingdom and CanadaCanada historically the Dominion of Canada is the second-largest, and northernmost, country in the world. It is a decentralized federation of 10 provinces and 3 territories, governed as a constitutional monarchy, and formed in 1867 through an act of Confe are the same as in the United States, and were unified to their current value in 1960.
In the United Kingdom, the pound was similarly defined as a unit of mass by the Weights and Measures Act of 1878, but having a very slightly different value (in relation to the kilogram) than it does now, of approximately 0.453592338 kg. This old value is sometimes called the imperial pound, and this definition and terminology are obsolete unless referring to the slightly-different 1878 definition.
A pound (troy) is a unit of mass in the United States, Canada, and United Kingdom. The troy pound is a unit of mass equalling exactly 0.3732417216 kilograms. There are 12 troy ounces in a troy pound. A troy pound is equal to exactly 5760 grains, making a troy pound equal to exactly 144/175 pounds. It is part of the troyTroy weight is a system of units of mass customarily used for precious metals and gemstones. It derives from the troy system of mass which dates back to before the time of William the Conqueror. Its name comes from the city of Troyes in France, an importa system of mass units.
The troy pound is used for measurements of precious metals such as gold, silver, and platinum. Any weight measurements of precious metals always uses troy pounds and ounces, even though it is not always explicitly stated that this is the case.
One troy pound = 12 troy ounces = 240 pennyweight.
A pennyweight was literally the weight of a penny, as adopted by King Henry IIHenry II ( March 25, 1133 July 6, 1189), ruled as Duke of Anjou and as King of England ( 1154 1189) and, at various times, controlled parts of Wales, Scotland, eastern Ireland, and western France. His sobriquets include "Curt Mantle" (because of the pract (1154–1189). This was a sterling silverSterling silver is at least 92. 5% silver and up to 7. 5% other metals, usually copper, and is stamped with either the word "Sterling" or ". 925" or the Lion Passant mark. Fine silver (99. 99% pure) is generally too soft for producing large functional obj penny weighing 1/240 of a troy pound.
