How to convert bigha to acres in Bihar

Multiply the number of bigha by 0.6249. For example, 5 bigha × 0.6249 = 3.1244 acres.

Every land unit is a fixed number of square feet: 1 bigha (Bihar) = 27,220 sq ft and 1 acre = 43,560 sq ft. Dividing the first by the second gives the conversion factor.

Is a bigha the same everywhere in Bihar?

Not always. The figure here is the one most commonly quoted for Bihar, but some districts and older records use a different bigha — often a larger ‘pucca’ and a smaller ‘kachha’ bigha. The area written in your land record and the survey map are what count legally, so use this as a guide and check the record before buying, selling or fencing.

Our Bihar land guide explains the local record (Jamabandi (Register II) and Khatiyan), where to check it online, and the risks NRI landowners there face.

Which figure should you trust in a dispute?

Conversions help you understand and compare; they don’t change what your record says. Trust the area in your record of rights and the survey map. If the land on the ground looks smaller than the record, the next step is a demarcation by the revenue office — and if you live abroad, satellite monitoring can flag field-scale change if a neighbour starts using your land.
