 METRIC WEIGHTS AND MEASURES The International System of Units (SI) All the systems of weights and measures whether they are metric or imperial are now audited through international agreements which support the International System of Units. The International System is called the SI or rather “Système International d'Unités”. In 1875 an agreement was signed  Convention du Mètre or “Treaty of the Metre” (notice Europeans commonly spell it differently from the USA who use ‘meter’) but because of such widespread usage of the term “meter” the “metre” is becoming less common even amongst Europeans. The USA is a charter member of the METRIC CLUB.
