Ampere the watt, the ohm and the volt. Rather than a definition in terms of the force between two current-carrying wires, it has been proposed that the ampere should be defined in terms of the rate of flow of elementary charges. Since a coulomb is approximately equal to elementary charges (such as those carried by protons, or the negative of those carried by electrons), one ampere is approximately equivalent to elementary charges moving past a boundary in one second. ( is the reciprocal of the value of the elementary charge in coulombs.) The proposed change would define 1 A as being
USS Ampere equipment was transferred to "USS Surfbird", a minesweeping vessel which was redesignated a degaussing ship on 15 June 1957. She remained in reserve in the Far East until the summer of 1961, when the decision was made to dispose of her. Her name was struck from the Naval Register on 1 July 1961, and she was sold on 21 June 1962, to the Philippine President Lines of Manila. Her final disposition is unknown. USS Ampere USS "Ampere" (PCE-919/AM-359/YDG-11/ADG-11) was originally planned as a for the United States Navy, "PCE-919", and laid down as an , named "Drake", for the male
