The bigha is a traditional unit of land in several parts of India, with land purchases still being undertaken in this unit. However, it varies in size from one part of India to another. It is usually less than one acre (0.4 hectares), but can extend up to 3 acres (1.2 hectares). In Imperial and SI Units, each Bigha is 968 yd 2 or 800 m 2. 2  In West Bengal, the Bigha was standardized under British colonial rule at 1600 yd 2 (0.1338 hectare or 0.3306 acre); this is often interpreted as being 1/3 acre (it is precisely 40 â 121 acre). 3  In metric units, a bigha is hence 1333 m 2.
