Bigha to Acre: State‑Wise Conversion Chart (UP, Bihar, Rajasthan, WB…)
You’re reading a land sale deed that says “5 Bigha”. But a Bigha in Rajasthan is almost three times larger than a Bigha in West Bengal. This is the biggest headache in Indian real estate — Bigha, Katha, Biswa, and Marla mean completely different sizes depending on which state you’re in. Before you finalise any land deal, you need the exact acre or hectare equivalent.
This article gives you a state‑wise conversion table and introduces a free tool that does the math instantly. Use our Land Area Converter to convert between Bigha, Acre, Hectare, and more in one click.
What Is a Bigha?
Bigha is a traditional unit of land measurement used across North and East India. Unlike standard units like Acre (4,046.86 sq m) and Hectare (10,000 sq m), Bigha has no fixed size. Each state historically defined it differently. Even within a state, “Pucca Bigha” and “Kachcha Bigha” exist. The most commonly accepted values are listed below.
State‑Wise Bigha to Acre Conversion
| State | 1 Bigha = Square Feet (approx) | 1 Bigha = Acre |
|---|---|---|
| Uttar Pradesh | 27,225 sq ft | 0.625 Acre |
| Bihar | 27,220 sq ft | 0.625 Acre |
| Rajasthan | 27,225 sq ft (Pucca) | 0.625 Acre |
| Madhya Pradesh | 12,000 sq ft (approx) | 0.275 Acre |
| West Bengal | 14,400 sq ft | 0.33 Acre |
| Gujarat | 17,424 sq ft | 0.4 Acre |
| Haryana / Punjab | 9,000 sq ft (Kachcha) | 0.207 Acre |
| Uttarakhand | 6,804 sq ft | 0.156 Acre |
Note: In UP and Bihar, 1 Bigha = 20 Biswa (or Katha). In MP, 1 Bigha = 20 Katha. Always verify the exact local measurement because land records sometimes use slightly different values.
Example Conversions
Example 1: A farmer in UP sells 4 Bigha land. In acres, that’s 4 × 0.625 = 2.5 Acres.
Example 2: A plot in Kolkata is advertised as 10 Bigha. In acres, 10 × 0.33 = 3.3 Acres.
How to Use the Land Area Converter
Go to Land Area Converter. Select the input unit (e.g., Bigha), choose the state (because the tool adjusts the conversion factor automatically), enter the value, and select the output unit (Acre, Hectare, etc.). The converter also handles square feet, square metres, and dismil. No manual calculations needed.
FAQ
1. Why does Bigha differ from state to state?
Because historically, local rulers and British administrators standardised land measurements differently. The metric system later added acres and hectares, but Bigha remained in popular use.
2. What is the difference between Pucca Bigha and Kachcha Bigha?
Pucca Bigha is larger and standardised (commonly 27,225 sq ft). Kachcha Bigha varies widely and is often 1/3 of a Pucca Bigha. Haryana’s Kachcha Bigha is around 9,000 sq ft. Always confirm which one the deed refers to.
3. Can I convert Bigha to Hectare directly?
Yes. 1 Acre = 0.404686 Hectare. First convert Bigha to Acre using the tool, then to Hectare — or the tool directly gives Hectare output.
4. Does the converter include South Indian land units?
It includes Acre, Hectare, Cent, Guntha, and Square Feet. For units like Ankanam, we are expanding the database. Use Acre as an intermediary.
