International metric standardsIn 1875, the International Bureau of Weights and Measures was established in Sèvres, France, by the International Metric Convention, (also known as the Treaty of the Meter), initially signed by representatives of 17 nations. Contributions from signatory goverments support the Bureau, which became the depository for the International Prototypes of the Meter and the Kilogram, and secondary standards. In French, it is known as the Bureau International des Poids et Mesures (BIPM). In subsequent years, additional nations joined, so by 2012 there are 53 member states, including all the major industrialized countries. The Convention thus provides the organizational structure for international agreements concerning matter relating to units of measurement. Each 20 May is now World Metrology Day.«[Original logo of the BIPM.]
