Among the first supporters for a metric system was an Englishman, Royal Society founder John Wilkins (1614-1672) in 1668. Gabriel Mouton also supported such a system in 1670. The foundation for the metric SI system (Système International d'Unités) was the "Metre Convention" signed by 17 countries on May 20, 1875.
In 1793, France adopted a meter as its official unit of length. From that time on we had metric rulers.

This question is based on a flawed assumption; the system was not discovered. To borrow some text from Wikipedia.org, "The metric system was conceived by a group of scientists (among them, Antoine-Laurent Lavoisier, who is known as the "father of modern chemistry") who had been commissioned by Louis XVI of France".
Many historians believe that the metric system was founded by Gabriel Mouton in 1670.

The French Revolution.
A committee composed of well-known French mathematicians devised the metric system with the meter as the basis. The centimeter is merely derived from the meter.

Metric system
The metric system was devised following the French Revolution and the metre was intended to be defined as one ten-millionth of the distance from the North Pole to the Equator. The centimetre is just one hundredth of a metre, using a system of prefixes as part of the metric system to define various lengths. In this case, the centi- prefix meaning one hundredth.
