1 In Assam, a bigha is 14,400 square feet (1,340 m 2), subdivided into five katha. 2  Each katha consists of 20 lecha with a lecha covering 144 square feet (13.4 m 2) in area, and hence each katha is 2,880 square feet (268 m 2) in area, although this may vary. 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.
