Its keystone became the "meter", a unit of length defined as one ten millionth of the distance from Earth's equator to the North Pole. In 1983, scientists redefined the meter as the distance traveled by light in a vacuum 1/299,792,458 of a second. This defined the meter more accurately but kept its length the same. "Meter" is derived from the Greek word meaning "a measure". The metric system was used sparingly by the French until January 1, 1840 when Napoleon Bonaparte made its use...
