The credit for the metric system goes to France. It all started in the year 1670 when Gabriel Mouton proposed a decimal system for conducting measurement which was based on a fraction of the Earth’s circumference. In later years a few mathematicians proposed their metric systems and in the year 1790 the National Assembly of France ordered the French Academy of Sciences to make a standard system of weights and measurements and in the year 1795 France successfully adopted the metric system.
