The French Revolution's Metric System: A Measure of Change

In 1793, as the French Revolution radicalized, a group of scientists and politicians embarked on a project to remake the world's measurements: the metric system. This episode follows the creation of the metre, defined as one ten-millionth of the distance from the North Pole to the Equator, and the survey that measured the meridian arc from Dunkirk to Barcelona, led by Jean-Baptiste Delambre and Pierre Méchain. But the road to the metre was pitted with obstacles: political upheaval, the guillotine falling on their patron Lavoisier, and Méchain's own embarrassing error. The episode also explores the system's initial public resistance, its eventual global adoption, and the surprisingly modern debates over decimal time and universal standards. Lucas and Luna unpack how a revolutionary ideal became the quiet backbone of science and trade. #FrenchRevolution #MetricSystem #Metre #Delambre #Mechain #Lavoisier #HistoryOfScience #WeightsAndMeasures #DecimalTime #MeridianArc #ParisMeridian #AcademieDesSciences #ConstituentAssembly #RevolutionaryFrance #Metrication #History #FexingoHistory #Europe Keep every episode free: buymeacoffee.com/fexingo
