Metric system

In 1795, France adopted by law, the metre as the unit of length and the base of the metric system. Since there had been no uniformity of French weights and measures prior to the Revolution, the Academy of Sciences had been charged on 8 May 1790 to organise a better system. Jean Delambre and Pierre Méchain measured an arc of the meridian from Dunkirk to Barcelona, so that the metre could be defined as one ten-millionth part of the distance between the poles and the equator.
