| 摘要： | After nearly 200 years of talking about metrication, the United States is slowly moving toward conversion. This article describes the long road to the 1991 Executive Order 12770, which mandates the transition to metric measurement by all federal agencies. The Federal Highway Administration (FHWA) implemented its 5-year conversion process, which includes five activities: 1) establishing basic plans and policies, 2) revising laws and regulations that impede metric conversion, 3) converting all FHWA documentation to metric, 4) converting all FHWA data collection and reporting systems, and 5) converting construction contracts, plans, and specifications. Metric training is scheduled nationwide, with FHWA and the Association of State Highway and Transportation Officials (AASHTO) as major sponsors. AASHTO is operating a metrication clearinghouse for state highway agencies as well. Sidebars explain the history of metrication in the United States and "hard" versus "soft" conversion. |
