Morgen

A Morgen (Mg) is a historical, but still occasionally used, German unit of area used in agriculture.

[1] The Morgen unit of land measurement was also used in the Netherlands, Poland, Lithuania, and parts of the Dutch colonial empire, such as South Africa.

[1][2] The morgen was usually defined as a rectangle with sides of an even number of local rods, as turning while ploughing was to be avoided as much as possible.

The area measure of the morgen varied regionally,[1] but it was usually between one-fifth to half a hectare (2,000 to 5,000 m²).

In the 20th century, the morgen, with its size of 25 ares, established itself as an agricultural area measure.

In November 2007, the South African Law Society published a conversion factor of 1 morgen = 0.856532 hectares to be used "for the conversion of areas from imperial units to metric, particularly when preparing consolidated diagrams by compilation".
