Metric system

In 1799, a second legal definition of the metre was made by the French National Assembly to be 3 feet and 11.296 lines of the toise of Paris (slightly tweaking the 7 Apr 1795 measure, and no meridian in the definition). The metric system was made compulsory by law in France. The toise of Paris refered to an old unit of lmeasurement, defined by the length of a specific standard metal bar held at Paris. (1 toise = 6 French feet, 1 ft = 12 in, 1 inch = 12 lines.) This second legal definition of the metre was used until it was replaced by a third legal definition made on 28 Sep 1889 by the Paris General Conference, when a new International protype metre bar was made of a platinum-iridium alloy. The 4th legal definition on 14 Oct 1960 used the wavelength of a spectral line of krypton.«
