The United States must commit to metrication. Two overwhelming factors, the adoption of the metric system by the remainder of the world and the changing global economy, mandate that this nation must change. This Guide has been written to provide an explanation of the need for the change, and to serve as a resource to help bridge the gap between building roads in the English-based system of units and the Metric system. It is intended that this guide be used as a reference manual for CDOT employees in the Right-Of-Way, Design, Bridge, Materials, Traffic, Maintenance, Planning, and Environmental areas.
