The story of the word

The French metric commission cut hect- out of ἑκατόν in 1795 and glued it to the are, from Latin area, producing a unit that is half Greek and half Latin. Purists objected then and were ignored, as they were later over television. A hectare is a square a hundred metres on a side, close to one and a half football pitches, and it replaced a mess of local units that measured land by how much a man could plough in a day.
