The metric system was invented in France during the late 18th century, with its origins credited to French scientists including Gabriel Mouton, an abbot who proposed a decimal system of measurement based on the Earth's dimensions in 1670, and chemists Antoine and Anne-Marie Lavoisier, who further developed the system for industrial use in the 1790s. The French National Assembly officially adopted the metric system in 1795, aiming to create a universal, decimal-based measurement system based on natural standards like the Earth's circumference.
