Bigha to Acre Converter – State-wise Bigha Standards
Bigha to Acre Converter
Convert plot sizes flawlessly using region-specific traditional metrics
Quick answer
A bigha to acre conversion depends on the state, because a bigha has no single size. Multiply the bigha by your local factor: in Punjab, Haryana and Himachal 1 bigha = 0.25 acre, so 10 bigha = 2.5 acres. In the UP standard used by this tool, 1 bigha = 0.625 acre, so 10 bigha = 6.25 acres.
Our free bigha to acre converter has the common state standards built in. Pick your region, enter the area, and it converts bigha to acres or acres to bigha, showing the constant and formula it used. It is useful for farmland deals, family partitions, loan papers and comparing listings from different states.
Why Does the Size of a Bigha Change?
The bigha is a traditional land unit used in India, Nepal and Bangladesh. It was defined locally long before metric or imperial units arrived, so its size varies from state to state and sometimes from district to district. Some regions even have a "pucca" (larger) and "kachha" (smaller) bigha. That is why any bigha to acre answer must start with the question: which bigha?
Bigha to Acre Standards Used in This Tool
| Region standard | 1 bigha in acres | 1 bigha in sq ft | Bigha in 1 acre |
|---|---|---|---|
| Punjab, Haryana and Himachal | 0.25 | 10,890 | 4 |
| Uttar Pradesh (UP standard) | 0.625 | 27,225 | 1.6 |
| Bihar and West Bengal | 0.3306 | about 14,400 | about 3.02 |
| Rajasthan and Gujarat | 0.4 | 17,424 | 2.5 |
| Uttarakhand / small bigha | 0.2 | 8,712 | 5 |
These are widely used reference values. Local land records can differ, especially in UP and Rajasthan, where pucca and kachha bigha both exist. Always confirm the size on your khatauni, jamabandi or sale deed before relying on any bigha to acre figure.
How to Use the Bigha to Acre Converter
Step 1: Select Your Region Standard
Keep Bigha to Acre selected and choose your state from the Select Region Standard State menu. Each option shows its bigha size in acres. We use Punjab, Haryana and Himachal (1 bigha = 0.25 acre).
Step 2: Enter the Area in Bigha
Type the land size into the box. Decimals work. In our example we enter 10 bigha.
Step 3: Click Convert Area
Press Convert Area. If the field is empty or negative, the tool asks for a valid area.
Step 4: Read the Result in Acres
The bigha to acre result shows 2.50 acres, with the constant (1 bigha = 0.25 acres) and the formula. Change the region and convert again to compare states.

| 5 | 1.25 | 3.125 | 1.653 | 2 | 1 |
| 10 | 2.5 | 6.25 | 3.306 | 4 | 2 |

| 50 | 12.5 | 31.25 | 16.53 | 20 | 10 |
Acre to Bigha
To go the other way, divide acres by the bigha size. With the Punjab standard, 1 acre = 1 ÷ 0.25 = 4 bigha, and 5 acres = 20 bigha. With the Rajasthan standard, 1 acre = 2.5 bigha. Click Acre to Bigha in the tool to do this automatically. For metric land units, try our hectare to acre converter.
Common Mistakes to Avoid
- Using one state's bigha for another. A UP bigha is two and a half times a Punjab bigha. The wrong standard gives a wildly wrong bigha to acre answer.
- Ignoring pucca and kachha bigha. Ask which one your records use.
- Mixing biswa and bigha. In many states 1 bigha = 20 biswa. Convert biswa to a decimal of a bigha first.
- Skipping square feet. For plots, convert acres to square feet with our acre to square feet converter and check against measured dimensions.
