Metric / Imperial Converter

Overview

metric ruler
In the late 18th century, Louis XVI of France charged a group of experts to develop a unified, natural and universal system of measurement to replace the disparate systems then in use. This group, which included such notables as Lavoisier, produced the metric system, which was then adopted by the revolutionary government of France. In the early metric system, there were several fundamental or base units, the grad or grade for angles, the meter for length, the gram for mass, and the liter for capacity.
