The Metre Convention is an international treaty signed in Paris by representatives of seventeen countries. It created the International Bureau of Weights and Measures, established at Sèvres near Paris, to provide for the unification and improvement of the metric system and to keep the international prototypes of the meter and the kilogram. A General Conference on Weights and Measures meets regularly to take decisions, and the convention has led to the International System of Units, the SI, in use worldwide. More than sixty states are now members. In 2019 the units were redefined in terms of fundamental constants, and the original platinum-iridium kilogram prototype ceased to be the definition of the kilogram.
