Why the same unit differs by state
Bigha, kattha and biswa are old local units. They were never fixed for the whole country, so a bigha in Uttar Pradesh (27,225 sq ft) is almost double a bigha in West Bengal or Assam (14,400 sq ft). Even inside a state, some districts use a different size.
Units like acre, hectare, square foot, square metre, gaj (square yard), cent, decimal and guntha have one fixed size everywhere.
Where our numbers come from
Every state value is checked against a source, mostly state revenue and land record departments and the Government of India land record data standard. The source is linked next to each unit.
For buying, selling or registration, always go by the area written in your land record or sale deed.
