Where Yard is UsedThe yard is mainly used in the United States, the United Kingdom and some other countries that have historical ties with them. It is used for measuring length, distance, area and volume in various contexts such as:
Definition of the YardThe current definition of the yard was established by an international agreement in 1959 as exactly 0.9144 meter. This definition was based on a prototype bronze bar that was forged in 1855 as an exact copy of the British Imperial Standard Yard held by Parliament. The prototype bar was called Bronze Yard No.11 and was the official standard of length for the United States until 1892. The yard is defined as the length of the path travelled by light in vacuum during a time interval of (1/299792458) × (3600/3937) seconds. This means that one yard is equal to 3600/3937 light seconds.History of the YardThe origin of the yard measure is uncertain. It may have derived from the old English unit of tax assessment called the yardland, which was equal to 1/4 hide or about 30 acres. It may also have derived from the old English unit of surveying called the rod, which was equal to 1/4 chain or about 16 (1/2) feet. The word “yard” comes from the old English word “gerd” or “gyrd”, which meant a branch, a staff or a measuring rod. The word “yard” was first used to describe this length in William Langland’s poem Piers Plowman in the late 14th century. The first official standard for the yard was established by King Henry I of England in the early 12th century. He ordered that the yard should be equal to the length of his arm from the tip of his nose to the end of his thumb. The yard was also used in other countries, such as Scotland, Ireland, France and Spain, with slight variations in length. For example, the Scottish yard was equal to 37 inches, the Irish yard was equal to 40 inches, the French yard was equal to 39.37 inches and the Spanish yard was equal to 32.38 inches. The yard underwent several changes and refinements over the centuries, until it was finally standardized as 0.9144 meter in 1959 by an international agreement between the United States, the United Kingdom, Canada, Australia, New Zealand and South Africa.
