Metre Convention - intro

The Metre Convention

The Metre Convention (Convention du Mètre) is the international treaty that forms the basis for international agreement on units of measurement. As well as founding the BIPM and laying down the way in which the activities of the BIPM should be financed and managed, it established a permanent organizational structure for member governments to act in common accord on all matters relating to units of measurement.

The Convention was signed in Paris on 20 May 1875 by representatives of seventeen nations, and revised slightly in 1921 to extend the scope and responsibilities of the BIPM.
