Morgen

A morgen was a unit of measurement of land in Germany, the Netherlands, Poland and the Dutch colonies, including South Africa and Taiwan. The size of a morgen varies from 1/2 to 2½ acres, which equals approximately 0.2 to 1 ha. It was also used in old Prussia, in the Balkans, Norway and Denmark, where it was equal to about two-thirds of an acre (0.27 ha).
