Core idea
Convert acres to bigha using a region’s standard. This tool uses the common “standard bigha” where 1 acre = 1.615 bigha.
How it works
Formula (standard bigha): Bigha = Acres × 1.615.
- Enter acres
- Multiply by 1.615
- Display rounds for readability; internal math keeps precision
Sanity checks
- 0 acres → 0 bigha
- 1 acre → 1.615 bigha
- 2 acres → 3.230 bigha
Shortcuts
- Half acre ≈ 0.8075 bigha
- 10 acres ≈ 16.15 bigha
- Back-convert quickly: Acres ≈ Bigha ÷ 1.615
Pitfalls
- Bigha varies by region (e.g., parts of WB/Assam use ≈3.025 bigha per acre)
- Always confirm the local definition for legal work
- Round only for display; keep full precision for records
Micro‑examples

- Do all states use 1.615? No—check local revenue standards
- Legal docs? Use the locally recognized conversion factor
Action tip
If your region uses a different bigha size, note it in your documents and apply that factor consistently.
