Customary units in India | Units of area
The bigha (also formerly beegah) is a traditional unit of measurement of area of a land, commonly used in India (including Uttarakhand, Haryana, Himachal Pradesh, Punjab, Madhya Pradesh, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Assam, Gujarat and Rajasthan but not in southern states of India), Bangladesh and Nepal. There is no "standard" size of bigha. The size of a bigha varies considerably from place to place. The size of Bigha is different in different areas. Sources have given measurements ranging from 1,500 to 6,771 square metres (16,150 to 72,880 sq ft), but in several smaller pockets, it can be as high as 12,400 square metres (133,000 sq ft). Its sub-unit is Biswa (or Bisa) or Katha (or Katta) in many regions. Again there is no "standard" size of biswa or katha. A bigha may have 5 to 200 biswa in different regions. (Wikipedia).
