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 American system of measurement is known as the U.S. customary system. Most of the units of measurement in the customary system are derived from British imperial units of measurement.
