Bigha
The bigha or beegah (Persian: بیگھا, Hindi: बीघा, Assamese: বিঘা) is a traditional unit of measurement of area of a land, commonly used in northern & eastern India, Bangladesh and Nepal. There is no "standard" size of bigha and it varies considerably from place to place.
Sources have given measurement of Bigha ranging from 6,805 square feet (632.2 m2) to 72,880 square feet (6,771 m2). Its sub-unit is Biswa or Katha in many regions, but it has no "standard" size. A bigha may have 5 to 20 Katha/ biswa in different regions.
