In , John Wilkins proposed a decimal system in which length, area, volume, and mass were linked to each other based on a pendulum that had a beat of one second as a base unit of length.

In , Gabriel Mouton proposed a decimal system that was instead based on the circumference of the earth, an idea supported by other prominent scientists of the time such as Jean Picard and Christiaan Huygens, but that did not take hold for approximately another years.

By the mid-eighteenth century, it was clear to nations who traded and exchanged scientific ideas that standardization of weights and measures was necessary. In , Charles Maurice de Talleyrand-Perigord, the Prince of Talleyrand, approached the British represented by John Riggs-Miller and the Americans represented by Thomas Jefferson with proposals to define a common standard of length based on the length of a pendulum.

In that same year, Thomas Jefferson, presented the "Plan for Establishing Uniformity in the Coinage, Weights, and Measures of the United States," which advocated for a decimal system in which units were related to each other by powers of ten.

A committee that was formed in France comprised of some of the most prominent scientists of the day came to a similar conclusion, and also proposed a decimal system for all weights and measures. Although Congress considered Jefferson's report, it was not adopted. As such, the measurement system was only implemented in France, and in , the metric system was formally defined in French law.

It was not until , however, that the metric system was officially adopted in France, though it was still not universally observed across the country. The spread of the metric system did not occur quickly, and areas that were annexed by France during Napoleon's reign were the first to adopt the metric system. By , two thirds of the European population, and nearly half the world's population had adopted the metric system.

The International System of Units, currently the most widely used system of measurement, was published in It has been adopted by all developed countries except for the United States, though as previously mentioned, it is used in science, as well as heavily in the military, even in the US.
