1911 Encyclopædia Britannica/Morgen

​MORGEN, a unit of measurement of land in Holland and the Dutch colonies, and hence still current in South Africa, equivalent to about 2 acres. It is also used in Prussia, Norway and Denmark, where it equals about two-thirds of an acre. The word is usually taken to be the same as the German and Dutch word for “morning,” the area of a “morgen” being equal, to that covered by a morning’s ploughing.
