U.S. prototype meter and kilogramIn 1890, the seals were broken on prototype meter No. 27 and prototype kilogram No. 20 in the Cabinet room of the Executive Mansion by U.S. President Benjamin Harrison, observed by the Secretary of State, the Secretary of the Treasury, and invited guests. Following the Metric Convention (20 May 1875), which the U.S. had signed, prototype measures had been prepared of platinum-iridium alloy from the international prototypes in France, and were ready for distribution on 26 Sep 1889. Two of each were furnished to the U.S.: kilograms Nos. 21 and 27, and meters Nos. 4 and 20. Those on which the seals were broken were thereby adopted as the U.S. national prototypes, which would thereafter be used to define all measurements of length and weight in the U.S.« |
