Convert bigha to acres — state by state
To convert bigha to acres, multiply by the size of one bigha in your state and divide by the size of one acre. Farm land is still bought and sold by the bigha across North and East India, while loans, crop schemes and land statistics use acres or hectares. This converter keeps the local definitions apart: pick the state or region first, then type in either box.
One bigha is anything from 0.15625 to 0.625 acres depending on where the land is, so a single “standard” figure from a search result can be badly wrong. Each value below says where it comes from — a state revenue rule or land-records publication where one exists, otherwise it is marked as a commonly used value that you should confirm with the tehsil, the sub-registrar or a licensed surveyor.
How to use the Bigha to Acre
- Choose the state or region at the top — the default is Rajasthan — 165 ft chain (Jaipur, Tonk, Alwar, Sikar, Jhunjhunu, Sawai Madhopur …).
- Type the area into the first box; the acres appear in the second box, in the result panel and in the formula line.
- Type into the second box instead to convert acres back to bigha, or press the swap button.
- Read the table to see the same area in every unit used in that state, with the basis of each value. Tap a row to make it the target unit.
- If your record uses a different size, pick Custom and enter the bigha, katha or marla size from your sale deed.
