The Metre Convention: a milestone that's changed modern life immeasurably.
This week marked the 150th anniversary of the Metre Convention, signed in Paris on 20 May, 1875 by 17 nations eager to bring order to a chaotic patchwork of global measurements.
The treaty established a universal system of units – ushering in consistency, accuracy, and international cooperation in science, industry and daily life.
