The History Of The S.I. System Of Units
The metric system began as the legal system of measurement in France during the 1800's. It was designed to replace the misunderstood and mixed-up units that were in use at the time.
Despite wars and international rivalries, the metric system has slowly spread throughout the world, although not all countries have completely adopted it. For example, England is only just changing weight system over to metric (as part of the formation of the European Union). The United States of America measure almost everything using the older imperial system of measurements, which includes things like the foot (for distance) and the pound (for weight). However, scientists in both countries use the metric system when communicating with the international scientific community.
