Kasson Act Law and Legal Definition

The Metric Act of 1866 is otherwise known as the Kasson Act, after Congressman John A. Kasson of Iowa, who chaired the House Committee on Coinage, Weights, and Measures. It was enacted on July 28, 1866. The Act is legally recognized as the metric system of measurement in the US. The 1866 Act includes a now-obsolete definition of the metric system and tables of units. It was amended by the America COMPETES Act (Pub. L. 110–69), which replaced the old definition of the metric system by the modern-day definition of SI. The Act is codified at 15 USC Section 204.
