As Ford's statement on the signing of the act emphasizes, all conversion was to be "completely voluntary."[1] The Act also established the United States Metric Board with representatives from scientific, technical, and educational institutions, as well as state and local governments to plan, coordinate, and educate the American people for the Metrication of the United States. Executive Order 12770, which cites the Metric Conversion Act of 1975, directed departments and agencies within the executive branch of the United States Government to "take all appropriate measures within their authority" to use the metric system "as the preferred system of weights and measures for United States trade and commerce." The metrification board was abolished in 1982 by President Ronald Reagan, largely on the suggestion of Frank Mankiewicz and Lyn Nofziger.[2]. See also
