Who Knew? While revolution raged, the metric system was born

the only countries that do not use the Metric system are Myanmar (also known as Burma), Liberia and the US. Why is the USA are so out of sync.

Who knew? We think of guillotines and Les Misérables. But a big part of the French Revolution was overthrowing the nobility’s ... feudal control of weights and measures. Early revolutionary sympathizer Marquis de Condorcet said only a universal measuring system would allow people to be “really equal in rights ... really free.” While revolution raged, the metric system was born, Nat Geo’s History magazine reports. And what of its aristocratic founder? Oh, the revolutionaries turned against him, and he died in prison. (detail from a 1795 engraving depicting people using the metric system.)
