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.
Oxgang
An oxgang was a medieval English unit of land area equal to approximately 60,703 m² (about 15 acres or 1/8 of a carucate).
Defined as the area one ox could plow in a year, equal to 1/8 of a carucate (which used 8 oxen).
Oxgangs appear in Domesday Book and other medieval English records. Obsolete by the late medieval period as land measurement moved to fixed surveyed units.
Anglo-Saxon English origin; obsolete by late medieval period.
