The Metric Conversion Act, as amended by the Omnibus Trade and Competitiveness Act (15 U.S.C. § 205), declares that the metric system is the preferred measurement system for U.S. trade and commerce. The Act requires each Federal agency to establish a date or dates in consultation with the Secretary of Commerce, when the metric system of measurement will be used in the agency’s procurements, grants, and other business-related activities. Metric implementation may take longer where the use of the system is initially impractical or likely to cause significant inefficiencies in the accomplishment of federally-funded activities. DOL shall follow the provisions of E.O. 12770, “Metric Usage in Federal Government Programs.”
