Units explained
Bigha (Kachha, North India)
A kachha (smaller) bigha is a traditional unit of land area used in North India, equal to approximately 1008 m² (about 0.25 acre). Used alongside the pucca bigha in Uttar Pradesh and Bihar.
The 'kachha' (raw or smaller) bigha is exactly one-third the size of the pucca bigha. Both units coexist in regional usage.
Kachha bighas appear in informal property descriptions and traditional land records in Uttar Pradesh and Bihar. Modern legal documents typically use hectares or pucca bighas with explicit conversion.
Traditional unit; relationship to pucca bigha standardized as 1:3.
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.
