of Standards created by an Act of Congress on March 3, 1901) in the Treasury Department as an office within the Coast Survey which was reorganized in 1832, where he carried out the early work of establishing the standards of weights and measures in the United States, with the involvement of fellow Swiss immigrant Albert Gallatin, then ambassador of the United States at London, who in 1827 had brought from Europe a troy pound of brass, made at his request by Henry Kater, from which the standard of mass was derived. This troy pound called troy pound of the United States' Mint at Philadelphia or Pound Troy, 1824 was used as the standard for the coining of money until the twentiest century. The avoirdupoids pound adopted by Hassler had 7000 grains, the Pound Troy,1824 having 5760 grains. In the autumn of 1829, Hassler was appointed as gauger in the New York Custom House. For some time Congress had been discussing the establishment of standard of weights and measure for the United States. Up to this time the various customhouses had worked independently of each other. They used separate weights and measures from wherever they could be obtained - most of them came from England - and in some cases the customhouses depended upon the ordinary standards of local officials. On 29 May 1829, the Senate decided a comparison of weights and measures used at customhouses. Five month later, President Andrew Jackson appointed Hassler United States gauger. With the approval of Secretary of the Treasury Samuel D. Ingham and President Jackson he determined to adopt standards for the United States and produce and distribute them to the customhouses. On 3 March 1831, Samuel D. Ingham reported to the President of the Senate Hassler's inspection far advanced and mentioned the Troughton scale as one of the authentic units adopted for the comparison. The Troughton scale was held to be identical with Bird's Standard Yard of 1760, which had been tested and deemed identical with the British Parliamentary Standard of 1758, which was destroyed in 1834. The fundamentals units of length, mass and capacity recommended by Hassler were adopted by the Treasury Department in 1832. Another meaningful national standard to be adopted in 1832 was the gallon at 231 cubic inches. Appraised by Treasury reports of Hassler's progress, Congress in a joint resolution of June 14, 1836, gave its formal approval and directed
