Metric System: The metric system is an internationally agreed decimal system of measurement created in France in 1799. The International System of Units (SI), the official system of measurement in almost every country in the world, is based upon the metric system.
The metric system was devised in France in the 18 th century. The goal was to replace the chaotic collection of units being in use with a system based on one common standard and simple decimal factors. The standard for length was defined equal to one ten-millionth of the distance between the North Pole and the Equator.
