Convert bigha to acres. Because a bigha's size differs by state, pick your state for an accurate result — the calculator also shows square feet and hectares.
A bigha is NOT standardised — its size varies by state and sometimes by district. Values here are the widely-cited state figures; always confirm the local definition and official land records before a transaction.
Unlike an acre (a fixed 43,560 sq ft), a bigha has no single value — it changes from state to state and sometimes between districts. This calculator lets you pick the state so the bigha-to-acre conversion is accurate for your region, and also shows the equivalent in square feet and hectares.
How bigha to acre is calculated
Each state defines a bigha as a certain number of square feet. Divide that by 43,560 (the square feet in one acre) to get acres.
Before standardised units, each region set its own land measures, and those definitions persist in local land dealings even though official records now use hectares or square metres. That's why one "bigha" in Rajasthan (27,225 sq ft) is nearly four times a bigha in Uttarakhand (6,804 sq ft). Some states also distinguish pucca (larger) and kachha (smaller) bigha. Always confirm the exact local definition before buying or selling land.
Frequently asked questions
How many acres is 1 bigha?
It depends on the state — roughly 0.62 acre in UP, 0.63 in Haryana/Rajasthan, but as little as 0.16 in Uttarakhand. Pick your state above for the exact figure.
Why does bigha vary by state?
Bigha is a traditional, non-standardised unit; each region historically defined it differently, and those definitions are still used locally.
What is pucca vs kachha bigha?
In Rajasthan, UP and Bihar, pucca (pakka) bigha is the larger, more commonly used measure; kachha bigha is smaller and was often used between landlords and tenants.
How many bigha in one acre?
Between about 1.6 (Rajasthan) and 6.4 (Uttarakhand) bigha per acre, depending on the state's bigha size.
Conversions are for general guidance. Traditional Indian land units vary by region and even by district; always confirm the local definition and official land records before any property transaction.
