Which Country Invented the Metric System?
A decimal-based measuring system was first proposed by a Flemish mathematician named Simon Stevin in 1586. The actual idea of a Metric system was first proposed by an Englishman, John Wilkins, of the Royal Society in London in 1688. But it didn’t catch on. Similar proposals were made by Gabriel Moulton in France (1694), a system based on the circumference of the earth, and Gottfried Leibniz of Germany France was the first country to actually adopt the Metric System as we know it in 1791.
