US Metric Association
The US Metric Association, based in Windsor, Colorado, is a non-profit organization that advocates for total conversion of the United States to the International System of Units. Founded on 27 December 1916 at Columbia University in New York City, it was originally called the American Metric Association. The USMA publishes a bi-monthly newsletter for its members on the state of the metric system in the United States called Metric Today.
Background
The Metric Act of 1866 declared the metric system to be "lawful throughout the United States of America" and in all business dealings and court proceedings, in essence allowing metric units to be used in an official capacity throughout America.At an international commercial congress, the Treaty of the Meter, also known as the Metre Convention of 1875, was signed by 17 countries, including the US, making the metric system the international system of weights and measures. Note that this was a meeting of international states to facilitate commerce. This treaty, then, falls under the overview of the United States Department of State, which has devolved oversight to the United States Department of Commerce.
The Mendenhall Order of 1893 scrapped the previously used standards and definitions for the yard, pound, gallon, and bushel. It adopted the standards of the metric system and redefined the yard, pound, gallon, and bushel in terms of metric units.
The Metric Conversion Act of 1975 started a voluntary metrication process in the US and, as amended by the Omnibus Foreign Trade and Competitiveness Act of 1988, declared the metric system to be "the preferred system of weights and measures for United States trade and commerce".
Mission
The US Metric Association advocates US conversion to the metric system, officially known as the International System of Units.In support of this mission, the USMA provides a public medium for information and discussion, reports of metrication within the US, a history of the use of metric units in the US, a related bibliography including relevant laws, an answer source for industrial inquiries, a cadre of people knowledgeable about the metric system, training aids and supplies for educators and the public, a certification program that has been used in industry, and various citations and awards for those supporting this mission.
The USMA is in cooperative communication with various state and federal governments, both legislative and executive, and various industrial and professional societies, such as the Institute of Electrical and Electronics Engineers, many of whom are involved in standards development.
