units and standards for expressing the amount of some quantity, such as length, capacity, or weight; the science of measurement standards and methods is known as metrology.
The basic units of the English system, the yard of length and the pound of mass, are now defined in terms of the metric standards, the meter of length and the kilogram of mass.
The federal government permitted the use of the metric system in 1866 and established a conversion table based on the yard and the pound; in 1893 the yard and the pound were redefined in terms of the metric prototypes of the meter and the kilogram.

 Units: The Metric System in the U. S.
Americans could have adopted the metric system, which was then at an uncertain point in its history; or they could have decided to align their measurements with the British Imperial measures established by Parliament in 1824 and thus created a possible alternative to the metric system in international commerce.
Proponents of the metric system in the U.S. often claim that "the United States, Liberia, and Burma (or Myanmar) are the only countries that have not adopted the metric system." This statement is not correct with respect to the U.S., and probably it isn't correct with respect to Liberia and Burma, either.
The U.S. adopted the metric system in 1866.

 Toward a Metric America: The United States and the Metric System   (Site not responding. Last check: 2007-10-20)
The metric system is a decimal-based system of measurement units.
In everyday usage, the most common metric units are the meter (m) to measure length, the second (s) to measure time, the kilogram (kg) for mass (or weight*), the liter (L) for volume, and the degree Celsius (°C) for temperature.
The metric system also avoids the use of multiple units for the same quantity; for instance, the inch-pound system's multiple units for volume include teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons.

The metric system originated in 1670 by Gabriel Mouton, a French vicar, as a reaction to the confusing and inconstant English system.
Although the system progressed slowly, by the mid- eighteenth century its logic was appreciated, culminating in the Treaty of the Meter in 1875, which establishedstandard metric measurements for 18 countries, including the United States.
The metrication of federal agencies is virtually complete, yet the general public of the United States still uses the English system as their principle means of measurement, creating a dichotomy between policy and general use.

Estimates also indicated that metric units were used in 75 percent to 85 percent of state administered highway construction projects in 1999.
Using the metric system would also eliminate the confusion between mass, force and weight with the use of the kilogram for mass and the Newton for force.
A “hard” metric dimension is attained by strictly designing and producing a product in metric dimensions, while a “soft” metric dimension is found by converting the dimensions of an already manufactured inch-pound product to an approximate equivalent metric dimension as would be the case with rebar, which would simply be renamed in metric dimensions.

 Metric System
The International System of Units, abbreviated SI (for the French name Système International d'Unités), is the most widely used system of units.
The metric system can legally be used in every country in the world (including the United States), and in many countries its use is obligatory.
The International System of Units was adopted by the 11th General Conference on Weights and Measures (CGPM) in 1960 and is built on the seven SI base units, which are used to define various SI derived units.

The metric system was conceived by a group of scientists (among them, Lavoisier) which had been commissioned by king Louis XVI of France to create a unified and rational system of measures.
The worldwide adoption of the metric system as a tool of economy and everyday commerce was based to some extent on the lack of customary systems in many countries to adequately describe some concepts, or as a result of an attempt to standardize the many regional variations in the customary system.
Since most non-SI units in common use, such as the U.S. customary units, are nowadays defined in terms of SI units, any change in the definition of the SI units results in a change of the definition of the older units as well.
