The legislation required most federal agencies to use the metric system in their procurement, grants, and other business-related activities by the end of 1992. [26] While not mandating metric use in the private sector, the federal government has sought to serve as a catalyst in the metric conversion of the country's trade, industry, and commerce.
The use of the metric system was made legal as a system of measurement in 1866 [165] and the United States was a founding member of the International Bureau of Weights and Measures in 1875. [166] The system was officially adopted by the federal government in 1975 for use in the military and government agencies, and as preferred system for trade ...
Before and in addition to the SI, other metric systems include: the MKS system of units and the MKSA systems, which are the direct forerunners of the SI; the centimetre–gram–second (CGS) system and its subtypes, the CGS electrostatic (cgs-esu) system, the CGS electromagnetic (cgs-emu) system, and their still-popular blend, the Gaussian ...

However, easily divisible numbers can be selected for use with metric units, e.g. 300 mm and its multiples. The number of times that these odd fractional numbers would come up has also been pointed out as a counterargument; in construction and engineering, for example, measurements would not only be likely to be in integers to begin with, but ...
In the metric system and other recent systems, underlying relationships between quantities, as expressed by formulae of physics such as Newton's laws of motion, is used to select a small number of base quantities for which a unit is defined for each, from which all other units may be derived. Secondary units (multiples and submultiples) are ...
Units in everyday use by country as of 2019 The history of the metric system began during the Age of Enlightenment with measures of length and weight derived from nature, along with their decimal multiples and fractions. The system became the standard of France and Europe within half a century. Other measures with unity ratios [Note 1] were added, and the system went on to be adopted across ...
In 1790, French diplomat Charles Maurice de Talleyrand-Périgord proposed that the fundamental unit of length for the metric system should be the length of a pendulum with a one-second period, measured at sea level on the 45th parallel (50 grades in the new angular measures), thus basing the metric system on the value of the second. A ...
