Pound sterling

The pound sterling (symbol: £; ISO code: GBP), commonly known simply as the pound, is the official currency of the United Kingdom, Jersey, Guernsey, the Isle of Man, South Georgia and the South Sandwich Islands, the British Antarctic Territory, and Tristan da Cunha. It is subdivided into 100 pence (singular: penny). A number of nations that do not use sterling also have currencies called the pound. At various times, the pound sterling was commodity money or bank notes backed by silver or gold, but it is currently fiat money, backed only by the economy in the areas where it is accepted. The pound sterling is the world's oldest currency still in use and which has been in continuous use since its inception.

The British Crown dependencies of Guernsey and Jersey produce their own local issues of sterling: "Guernsey pound" and "Jersey pound". The pound sterling is also used in the Isle of Man (alongside the Manx pound),Gibraltar (alongside the Gibraltar pound), the Falkland Islands (alongside the Falkland Islands pound), Saint Helena and Ascension Island in Saint Helena, Ascension and Tristan da Cunha (alongside the Saint Helena pound). The Bank of England is the central bank for the pound sterling, issuing its own coins and banknotes, and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. Banknotes issued by other jurisdictions are not regulated by the Bank of England; local governments use Bank of England notes as backing for local issuance by allowing them to be exchanged 1:1 at face value.

Pound (mass)

The pound or pound-mass (abbreviations: lb, lb_m, lbm, ℔) is a unit of mass used in the imperial, United States customary and other systems of measurement. A number of different definitions have been used, the most common today being the international avoirdupois pound which is legally defined as exactly 6999453592370000000♠0.45359237 kilograms, and which is divided into 16 avoirdupois ounces.

The unit is descended from the Roman libra (hence the abbreviation "lb"); the name pound is a Germanic adaptation of the Latin phrase libra pondo, "a pound by weight".

Usage of the unqualified term pound reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms pound-mass and pound-force.

Current use

The United States and countries of the Commonwealth of Nations agreed upon common definitions for the pound and the yard. Since 1 July 1959, the international avoirdupois pound has been defined as exactly 6999453592370000000♠0.45359237 kg.

In the United Kingdom, the use of the international pound was implemented in the Weights and Measures Act 1963.
