In the metric system, which was established in France by law in 17 95, and is now widely adopted for commercial purposes, the standards of length and mass are the Metre and the Kilogramme, respectively. The Metre is the distance between the ends of a rod of platinum made by Borda, when the temperature is that of melting ice: the Kilogramme is the mass of a piece of platinum, also made by Borda.
