Mesures usuelles (French pronunciation: [məzyʁ yzɥɛl], customary measurements) were a French system of measurement introduced by French Emperor Napoleon I in 1812 to act as compromise between the metric system and traditional measurements. The system was restricted to use in the retail industry and continued in use until 1840, when the laws of measurement from 1795 and 1799 were reinstituted.[1]
