Units explained
Carucate
A carucate was a medieval English unit of land area equal to approximately 485,623 m² (about 120 acres or 48.6 hectares).
Originated in early medieval England as the area one team of eight oxen could plow in a year. The size varied considerably by soil type and region.
Carucates appear in the Domesday Book and other medieval English land surveys. The unit was used for taxation assessment but was inherently variable due to its agricultural-output basis.
Anglo-Saxon English origin; obsolete by late medieval period.
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.
