On 7 April 1795, the metric system was formally defined in French law. [Note 10] It defined six new decimal units: [26] The mètre, for length—defined as one ten-millionth of the distance between the North Pole and the Equator through Paris; The are (100 m 2) for area [of land] The stère (1 m 3) for volume of firewood
Its changeover lasted from 1 April 1960, when metric measurements became legal, to 1 April 1962, when all other systems were banned. The Indian model was extremely successful and was copied over much of the developing world. Two industrialized Commonwealth countries, Australia and New Zealand, also did a quick conversion to metric.
[7] 1976 – The building and construction industry completed its change to metric measurements (within two years) by January. 1977 – All packaged goods were labelled in metric units, and the air transport, food, energy, machine tool, electronic, electrical engineering, and appliance manufacturing industries converted to metric.
The U.S. military, reflecting its need to ensure interoperability with its NATO allies, uses metric measurements for almost all weapons calibers, even for calibers that originated as or were derived from a different measurement (e.g., 7.62 mm rather than .308, or 5.56 mm instead of .223). However, civilian rifles chambered for .223 Remington ...

Signs like these do not comply with legislation, as metric prices must not be less prominent. [1] [2] Metrication is the act or process of converting to the metric system of measurement.
The metric system is a system of measurement that standardizes a set of base units and a nomenclature for describing relatively large and small quantities via decimal-based multiplicative unit prefixes.
To give metrication a human face, a baby girl whose parents agreed to co-operate was nicknamed Miss Metric. [2] News and pictures of her progress were intermingled with press releases about the progress of metrication. By the end of 1972 the temperature scale, road signs, and measures used in the sale of such items as wool and milk had been ...
[3] 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.
