Units explained
Bigha (Assam)
An Assam bigha is a traditional unit of land area used in Assam and parts of Northeast India, equal to approximately 1337.8 m² (functionally identical to the Bengal bigha).
Derived from the same colonial Bengali standardization that produced the Bengal bigha. Assam land records share much of Bengal's traditional unit system.
Assam bighas are used in property transactions and agricultural records across Assam and several other Northeast states. The unit equals 14,400 sq ft.
Standardized in colonial Bengal/Northeast India administration.
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.
