The Arabs used coins as a measurement of units of weight since a minted coin could not easily be cut or shaved to reduce its weight, and thus provided a measurable standard.

They used a coin called a silver dirhem as a basic measure of weight, which had a weight roughly equivalent to 45 fully grown grains of barley. Ten dirhems comprised a Wukryeh, which was translated into Latin as an "uncia" — the origin of the word "ounce. Over time, trade spread from the Mediterranean area to Europe, including the northern German City States.

As a result, a pound, 16 ounces of silver, or grains, became a commonly used measure in many regions. While England also adopted this measure, a shortage of silver caused King Offa to reduce the measurement of the pound to grains in order to use smaller coins.

Eventually, when William the Conqueror became King of England, he retained the grain pound for minting coins, but reverted to the grain pound for other purposes. Though many countries used the pound from that point onward, including England the British pound sterling, or GBP was equal to one pound-weight of silver in King Offa's time , the avoirdupois weight system was adopted during the reign of Queen Elizabeth in the 16th century.

It was a system based on the weight of coal, and its name was derived from the French phrase "avoir de pois" goods of weight or property.
