Important: the size of a katha or bigha can vary by region. This converter uses the standard values most widely used in Bangladesh (1 katha = 720 sq ft, 1 bigha = 20 katha). Bigha and katha sizes in different Indian states are very different. Regional units such as kani, gonda and kora vary so much from place to place that we have not included them. For buying, selling or registering land, the measurement of your local land office or surveyor is final.

Examples

1 bigha = 14,400 sq ft = about 33.06 decimals = 0.33 acre. 5 katha = 3,600 sq ft = about 8.26 decimals.
