Bigha to Acre, Acre to Bigha, and Every Other Indian Land Unit

India uses a mix of metric units (square meter, hectare) and traditional regional units (bigha, guntha, kanal, marla, cent, ground, kattha) for land measurement. Unlike most countries, there is no single nationwide land unit, and one bigha in Bihar is not the same as one bigha in Himachal Pradesh. This converter lets you switch between all common Indian land units with state-specific bigha values, so whether you are reading a revenue record, evaluating a property listing, or dividing ancestral land, you get the correct conversion without guessing.

For a quick reference: one standard Pucca bigha (used in Bihar, eastern UP, and Rajasthan Pucca tradition) equals about 2,529 square meters or 27,225 square feet, which works out to roughly 0.625 acres. One acre in return is about 1.6 bigha in these states. The state-wise table inside the tool above lists the exact value for 13 bigha variants plus 7 other regional units.

How Many Bigha Are There in One Acre?

The difference matters in practice. A deed saying "10 bigha of land" in Himachal Pradesh represents about 2 acres, while the same phrasing in Rajasthan Pucca country represents about 6.25 acres. Buyers, sellers, inheritors, and tax assessors all need to confirm which regional convention the deed follows.

How to Convert Bigha to Acre (Formula)

Once you know which bigha value applies in your state, the formula is straightforward:

Worked example: converting 10 bigha in Bihar to acres.

• 1 Bihar bigha = 2,529.28 square meters
• 10 bigha = 10 × 2,529.28 = 25,292.8 square meters
• 1 acre = 4,046.86 square meters
• 25,292.8 ÷ 4,046.86 = 6.25 acres

How to Convert Acre to Bigha (Reverse)

Going the other way - acre to bigha - is the most-searched reverse query. The formula:

Worked example: 1 acre in West Bengal bigha.

• 1 West Bengal bigha = 1,340 square meters
• 1 acre = 4,046.86 square meters
• 4,046.86 ÷ 1,340 = 3.02 bigha
• In Bengal, 1 acre is roughly 3 bigha.

Other Indian Land Units Explained

Hectare vs Acre vs Bigha - When to Use Which

Hectare (10,000 sqm) is the official metric unit used in Indian government land records since 1957, in agricultural statistics, and in court orders. One hectare equals 2.47 acres.

Acre (4,046.86 sqm) is the English imperial unit used widely in private land dealings, real estate listings, and colonial-era revenue records that have not been converted to metric. Agricultural economists often use acres.

Bigha and other traditional units (guntha, cent, kanal, marla) are used in everyday rural and small-town dealings, old family records, and many state-level revenue documents. They remain legally valid for local transactions in most states but the official record of rights increasingly expresses area in square meters or hectares. Always confirm the conversion with your local revenue office before legal registration.
