The story of the word

The revolutionary committee that built the metric system in 1795 did not invent the name. They took litron, an old French dry measure, and clipped it; litron traces back through Medieval Latin to λίτρα, a unit of weight and a silver coin used by the Greeks of Sicily. λίτρα and Latin libra are usually explained as two borrowings of one older Mediterranean word rather than as relatives.
