This conversion is essential for farmers, landowners, and real estate professionals across the Indian subcontinent.
- Start with the area in acres.
- Multiply by 1.6133 (for the standard/UP bigha).
- The result is the area in bigha.
- Note: This factor varies by state — always verify which regional bigha is intended.

Regional Variations of the Bigha
The bigha has no single national standard and varies dramatically by region. In Uttar Pradesh and Bihar, 1 bigha = 20 biswa = approximately 27,000 sq ft (so 1 acre ≈ 1.6 bigha). In Rajasthan, 1 bigha = 1,618.7 m² (similar to UP). In Assam, 1 bigha = 14,400 sq ft (so 1 acre ≈ 3 bigha). In West Bengal, 1 bigha = 14,400 sq ft as well. In Gujarat, the bigha is approximately 17,427 sq ft. Always verify which regional definition applies before any land transaction.
Land Revenue and Agricultural Surveys
Indian land revenue records (khatauni, khasra) often list areas in bigha-biswa format. When these records interface with modern satellite-surveyed maps (in acres or hectares), conversion is necessary. The government's Digital India Land Records Modernization Programme (DILRMP) is gradually standardizing measurements to metric, but millions of existing records remain in bigha. Farmers applying for crop insurance, subsidies, or bank loans must often convert between bigha and acres for official forms.
Key Takeaways
- 1 acre ≈ 1.6133 bigha (UP/Bihar standard).
- The bigha varies by region — Assam and Bengal use a smaller bigha (1 acre ≈ 3 bigha).
- Always confirm the local standard before converting.
- Indian land revenue records use bigha-biswa; official forms use acres or hectares.
- Land modernization programs are moving toward metric, but bigha remains in everyday use.
