Metre Convention
After the Second World War the International Union of Pure and Applied Physics (IUPAP) and the French Government asked the BIPM to look into the matter. In 1948, the 9th CGPM asked the CIPM to conduct a study into units of measurement used by member states. The CIPM reported back and in 1954 the 10th CGPM decided to set up a new system of units. There would be six base units. These were the metre, kilogram, second, ampere, degree Kelvin (later renamed kelvin), and candela. The new system was published in 1960.  The 11th CGPM named it the International System of Units. The short name was "SI".  This came from the French name, . The BIPM described SI as "the modern metric system".
