In 1901, the Office of Weights and Measures (OWM) moved from its home in the Coast and Geodetic Survey Building on New Jersey Avenue in the District of Columbia to the Butler Building next door. This was a temporary location for OWM [renamed the Weights and Measures Section] while it waited for its new uptown quarters on the National Bureau of Standards (NBS) campus to be built. The South Building was complete in 1904, and the NBS Weights and Measures Section occupied a laboratory on the ground floor.
