United States Metric Board

The United States Metric Board (USMB) was a United States government agency set up to encourage metrication. The United States Metric Board was commissioned by the Metric Conversion Act, 15 U.S.C. 205d, enacted on December 23, 1975. The Metric Conversion Act of 1975 mandated the presidential appointment of seventeen members for the "independent instrumentality".

The metrification assessment board existed from 1975 to 1982, ending when President Ronald Reagan abolished it, largely on the recommendation of Frank Mankiewicz and Lyn Nofziger. Overall, it made little impact on implementing the metric system in the United States.
