Bigha is a traditional unit of land measurement that was not standardized before the British era. Consequently, different states established their own local equivalents based on custom (e.g. 1 Bigha is 27,225 sq ft in UP, but 14,400 sq ft in West Bengal).
There are exactly 43,560 Square Feet in one standard Acre.
In most standard measurement systems in Bihar, UP, and Bengal, 1 Bigha is divided into exactly 20 Katha.
One Hectare is equivalent to approximately 2.471 Acres.
Gaj is the Hindi term for Square Yard. One Gaj is equal to 9 Square Feet. (e.g. a 100 Gaj plot is 900 Square Feet).
Multiply the length of the plot by its width (Length * Width) in feet to get the area in Square Feet. Then convert that value to Bigha or Acres using our converter.
Biswa is a sub-unit of Bigha used in Northern India (UP, Punjab, Haryana). Generally, 1 Bigha is equal to 20 Biswa.
