What is the metric system? • The first standardized system of measurement, based on the decimal was proposed in France about 1670. • It was created to develop a unified, natural, universal system of measurement. • In 1790 King Louis XVI of France assigned a group to begin this task. • At that time, every country had their own system of weights and measures. England had three different systems just within its own borders!! • It was called the "metric" system, based on the French word for measure. • As of 2005, only three countries, the United States, Liberia, and Myanmar, have not changed over to the metric system. • The official modern name of the metric system is the International System of Units or abbreviated SI.
