MetreIn 1983, the fifth legal definition of the metre was the the distance that light travels in a vacuum in 1/299,792,458 of a second. length of the meter was redefined at the 17th meeting of the international body Conférence Générale des Poids et Mesures (GCPM) by a method to give greater accuracy. It superceded the fourth legal definition adopted on 14 Oct 1960 based on a spectral line of kryton. Earlier definitions included the distance between marks on the international prototype metre bar made of platinum-iridium alloy (28 Sep 1889). Before that, the metre was decided that it should be one ten-millionth of the distance from the North Pole to the equator (1 Aug 1793), and the earliest concept was the length of a pendulum with a half-period of one second (8 May 1790).«
