The acre to bigha converter provides accurate, state-specific land area conversions for Indian property measurement. Bigha sizes vary dramatically across states — always select your region first for correct results.
Unlike standardised units, a bigha has no single definition. Its size varies from state to state in India, making it essential to know which bigha you’re converting to. This calculator includes the correct conversion rate for every major Indian state.

In Rajasthan, land is measured using two bigha sizes. Pucca bigha is the larger unit at 2,529.3 m², used in official land records. Kaccha bigha is roughly 40% of a pucca bigha (about 1,011.7 m²), used in rural and informal transactions. Always confirm which type applies to your deal.
Bigha originated as a feudal land measurement that was never standardised under British or post-independence Indian law. Each princely state and region maintained its own definition. Even today, local tehsil offices use the regional bigha size in revenue records. If you’re buying land across state borders, always verify the local bigha definition with the sub-registrar.
Bigha was never standardized across India. Different states and former princely regions adopted their own measurements, and many of those local standards remain in use today. Even neighboring districts may use slightly different values, so always verify the local conversion before buying or selling land.
Pucca bigha is the officially recognized measurement used in many land records, while kaccha bigha is a smaller traditional unit used in some rural areas. Their exact sizes vary by region, so make sure you know which version is being referenced during any land transaction.
Yes. Many northern and eastern Indian states still use bigha in revenue records, often alongside hectares or square metres. However, legal documents and modern registrations increasingly include metric units for consistency.
Most southern Indian states, including Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, and Telangana, generally use units such as acres, cents, grounds, or gunthas instead of bigha.
There is no single answer because the size of a bigha differs by state. One hectare equals approximately 3.95 bigha in parts of Uttar Pradesh, around 7.48 bigha in West Bengal, and different values elsewhere. Always select the correct regional conversion.
