The international yard was about two millionths of a meter longer than the imperial yard, while the international pound was about six ten-millionths of a kilogram lighter than the imperial pound. [13] The metric-based international yard and international pound were adopted by the United States National Bureau of Standards effective 1 July 1959.
The standard yard and pound were lost in 1834 when a fire partially destroyed the Palace of Westminster. Following a report published in 1841 by a commission new standard yard and pound were manufactured using the best available secondary sources. Unlike the previous standard, the new pound standard was a pound avoirdupois.
These definitions were refined by the international yard and pound agreement of 1959. [4] The United States uses customary units in commercial activities, as well as for personal and social use. In science, medicine, many sectors of industry, and some government and military areas, metric units are used.
The international yard is defined as exactly 0.9144 metres. This definition was approved by the United States, Canada, the United Kingdom, South Africa, Australia and New Zealand through the international yard and pound agreement of 1959, and corresponds with the previous 1930s British and American definitions of 1 inch being 25.4 mm.

The current international standard for the metric system is the International System of Units (Système international d'unités or SI). It is a system in which all units can be expressed in terms of seven units. The units that serve as the SI base units are the metre, kilogram, second, ampere, kelvin, mole, and candela.
The last Imperial Standard Yard in bronze was made in 1845; it served as the standard in the United Kingdom until the yard was redefined by the international yard and pound agreement (as 0.9144 metres) in 1959 (statutory implementation was in the Weights and Measures Act 1963).
The international yard and pound agreement of July 1959 defined the length of the international yard in the United States and countries of the Commonwealth of Nations as exactly 0.9144 meters. Consequently, since a foot is one third of a yard, the international foot is defined to be equal to exactly 0.3048 meters.
[3] [4] [5] 3 qr. was a Flemish ell, 4 quarters were a yard, 5 qr. was an (English) ell, and 6 qr. was an aune or French ell. [3] [4] Each quarter was made up of 4 nails. [3] [4] Its metric equivalent was formerly reckoned as about 0.228596 m, [5] but the International Yard and Pound Agreement set it as 0.2286 exactly in 1959. [a]
