Units explained
Acre
An acre is an imperial unit of area equal to exactly 4046.8564224 m². It is the most widely used non-metric unit for land area, particularly in the US, UK, and India.
Originally defined in medieval England as the area one yoke of oxen could plow in a day, approximately 40 perches by 4 perches. Standardized via the 1959 International Yard and Pound Agreement.
Acres are the standard land measurement unit in the US (real estate, agriculture), the UK (rural property), and widely used in India (alongside hectares and traditional regional units). 1 acre = 4840 sq yd = 43,560 sq ft = 0.4047 hectare.
Medieval English farming origin; modern exact value standardized in 1959.
Morgen (South Africa)
A South African morgen is a unit of land area equal to approximately 8565.32 m² (about 0.857 hectare or 2.12 acres).
Originated from the Dutch (and earlier German) morgen, originally meaning 'the area one ox could plow in a morning'. South Africa standardized the unit at 600 Cape roods × Cape rood width.
South African morgens appear in legal land descriptions, particularly for rural and historical properties. Although officially superseded by hectares, the unit remains in some older documents.
Traditional Dutch/Afrikaner unit; standardized in South African colonial administration.
