Checking Local Land Units Before You Trust an Acre to Bigha Converter
An acre is a fixed unit: 43,560 square feet, or about 4,046.86 square metres, everywhere it is used. A bigha is not. It is a traditional measure, and its size changes from state to state and sometimes between districts or even villages within one state. That is why a state-wise conversion only gives you a starting point, and why two people quoting “one bigha” may be describing very different plots.
Before you rely on a number for a sale, a loan or a family division of land, work through these checks.
- Read the land record. Documents such as the khatauni, jamabandi, record of rights or sale deed often state the area in square metres, hectares or acres as well as local units. Use that official figure as your anchor.
- Ask which bigha is meant. In some areas a “pucca” and a “kachha” bigha are both in use, and they are not the same size. Clarify with the seller, the patwari or the local revenue office.
- Convert through square feet or square metres. If a document gives the local bigha in square feet, divide the acreage in square feet by that figure. This avoids stacking several rounded conversions.
- Keep sub-units in mind. Biswa, katha and dhur divide a bigha differently by region, so a figure like “2 bigha 5 biswa” needs the local ratio as well.
Rounding matters more than it looks. Land prices are often quoted per bigha, so a small difference in the assumed size multiplies across a large plot. Carry at least two decimal places through the calculation and round only the final answer. When comparing two offers, convert both to the same unit, ideally square metres or acres, and compare price per unit rather than price per bigha. This removes any doubt about which local bigha each seller had in mind, and it makes offers from different states or districts directly comparable.
The bigha article on Wikipedia lists many of the regional sizes and shows how widely they vary. Use an acre to bigha converter for quick planning and comparison, then confirm the exact area with the land records office or a licensed surveyor before any legal or financial step. Measurements recorded in official documents always take priority over an online estimate.
