Hectare to Bigha in Assam
If you've ever tried to buy or sell land in Assam, you already know how confusing it gets when the seller quotes the area in bigha and the government records show hectares. These are two completely different units, and unless you know the exact conversion for Assam specifically, you're going to end up either overpaying or losing out on a deal.
This isn't a generic land conversion article. This is specifically about how bigha is measured in Assam, what 1 hectare equals in Assam's local bigha unit, and how to quickly convert between the two without making a mistake.
How Many Bigha in 1 Hectare in Assam?
1 Hectare = 7.4759 Bigha in Assam
That's the number you need to remember. If you're going the other way, 1 Bigha in Assam equals approximately 0.1338 hectares.
This conversion is specific to Assam. The bigha unit is not uniform across India. Bihar bigha, Rajasthan bigha, and West Bengal bigha are all different sizes. Assam has its own defined bigha, and mixing it up with another state's bigha is a common mistake that causes real confusion in land transactions.
Hectare to Bigha Conversion Table for Assam
Here's a quick reference table so you don't have to do the math every single time:
| Hectare | Bigha (Assam) |
|---|---|
| 0.5 | 3.74 |
| 1 | 7.48 |
| 2 | 14.95 |
| 3 | 22.43 |
| 5 | 37.38 |
| 10 | 74.76 |
| 20 | 149.52 |
| 50 | 373.80 |
| 100 | 747.59 |
You can use these figures as a reference whether you're checking land records, calculating agricultural area, or negotiating a property deal.
The Conversion Formula
The math is straightforward once you have the conversion factor:
Bigha (Assam) = Hectare × 7.4759
And for the reverse:
Hectare = Bigha (Assam) × 0.1338
Quick Example
Say you're looking at a piece of agricultural land in Goalpara district that the seller says is 4 bigha. You want to know that in hectares.
4 × 0.1338 = 0.5352 hectares
Or if the land records at the revenue office show 2.5 hectares and you want to tell your family how big it is in the local bigha unit:
2.5 × 7.4759 = 18.69 bigha
Simple, right? The formula doesn't change. Just make sure you're using the Assam-specific factor and not some generic number you found on a unit converter website that doesn't specify the state.
Why Assam Bigha Is Different From Other States
This is the part most people skip, and then they get confused later.
In India, bigha is what's called a traditional unit of land measurement. Unlike meters or hectares, it was never standardized nationally. Each region, and sometimes each district within a region, historically used its own version of bigha.
Over time, many state governments defined official bigha sizes for land records. In Assam, the government-recognized bigha works out to approximately 1,337.8 square meters or 14,400 square feet.
Compare that to some other states:
- Bihar: 1 bigha ≈ 2,500 sq. meters (much larger)
- Rajasthan: 1 bigha ≈ 1,618 sq. meters
- West Bengal: 1 bigha ≈ 1,333 sq. meters (close to Assam but not identical)
- Uttar Pradesh: 1 bigha ≈ 2,529 sq. meters
So when someone from Bihar tells you they have 5 bigha of land, that's a very different amount than 5 bigha in Assam. The word is the same, the size is not.
What Is a Hectare?
A hectare is an internationally standardized unit used in government land records, forest surveys, and agriculture reports across India. 1 hectare = 10,000 square meters. It's part of the metric system, which is why official documents like patta, jamabandi, and revenue records increasingly use hectares.
In Assam's land records maintained by the state revenue department, agricultural land is often recorded in hectares, while locals still prefer bigha for everyday conversation and transactions. This gap between official records and local usage is exactly why knowing this conversion matters.
How Assam Land Records Work
In Assam, land records are maintained by the Directorate of Land Records and Survey under the Revenue Department. The key document you'll encounter is the Jamabandi (also called patta), which records ownership and area of land.
The area in Jamabandi is typically shown in bigha, katha, and lecha, which are the traditional sub-units used in Assam.
Assam Land Sub-Units Explained
Here's how the Assam land measurement hierarchy works:
- 1 Bigha = 5 Katha
- 1 Katha = 20 Lecha
- 1 Bigha = 100 Lecha
- 1 Bigha ≈ 1,337.8 sq. meters
- 1 Katha ≈ 267.56 sq. meters
- 1 Lecha ≈ 13.38 sq. meters
When you're reading a land document in Assam, you'll often see area written as something like "2 Bigha 3 Katha 10 Lecha." Converting all of that to hectares means you'll need to convert each sub-unit separately and add them up.
Converting Katha and Lecha to Hectares
Since katha and lecha are parts of a bigha, the math flows the same way:
- 1 Katha = 0.02676 Hectares
- 1 Lecha = 0.001338 Hectares
So if you have a plot of 1 Bigha 2 Katha, that's:
(1 × 0.1338) + (2 × 0.02676) = 0.1338 + 0.05352 = 0.1873 hectares
Practical Situations Where This Conversion Matters
Buying Agricultural Land in Assam
Agricultural land in districts like Kamrup, Nagaon, Dibrugarh, and Jorhat is still quoted and sold in bigha. If you're purchasing land and the government valuation or bank loan documents show the area in hectares, you need to cross-verify that the numbers match what the seller is telling you.
A seller quoting 10 bigha should match approximately 1.338 hectares in the official record. If the figures don't line up, something needs to be checked before you sign anything.
Agricultural Schemes and Subsidies
Many central and state government agricultural schemes, including PM-KISAN and state-level crop insurance programs, calculate land eligibility in hectares. A farmer who knows his land is 5 bigha needs to report approximately 0.669 hectares on the application form. Getting this wrong can affect your eligibility or the subsidy amount you receive.
Revenue Court Documentation
If you're involved in any land dispute, mutation, or partition case in Assam's revenue courts, the documentation will mix both units. Being able to convert accurately helps you verify that the legal description of the land matches what you're claiming or contesting.
Hectare to Bigha Conversion in Assam vs Neighbouring States
Since Assam shares borders with states like West Bengal, Arunachal Pradesh, and Meghalaya, cross-border land matters do come up. Here's a quick comparison so you're not caught off guard:
| State | 1 Hectare in Bigha (Approx.) | 1 Bigha in Sq. Meters (Approx.) |
|---|---|---|
| Assam | 7.4759 | 1,337.8 |
| West Bengal | 7.4956 | 1,333.3 |
| Bihar | 3.9536 | 2,529.3 |
| Rajasthan | 6.1776 | 1,618.7 |
| Uttar Pradesh | 3.9536 | 2,529.3 |
You'll notice Assam and West Bengal are quite close, but they're not identical. Don't assume they're interchangeable just because the numbers look similar at first glance.
Frequently Asked Questions
How many bigha is 1 hectare in Assam?
1 hectare equals 7.4759 bigha in Assam. This is based on Assam's local bigha, which is approximately 1,337.8 square meters.
Is bigha the same in Assam and West Bengal?
Not exactly. Assam bigha is approximately 1,337.8 sq. meters and West Bengal bigha is approximately 1,333.3 sq. meters. They're very close but not identical, so the conversion factors differ slightly.
How many katha in 1 hectare in Assam?
Since 1 bigha = 5 katha in Assam, and 1 hectare = 7.4759 bigha, you get: 1 hectare = 7.4759 × 5 = 37.38 katha.
How many lecha in 1 hectare in Assam?
1 bigha = 100 lecha in Assam. So 1 hectare = 7.4759 × 100 = 747.59 lecha.
What is 5 bigha in hectare in Assam?
5 bigha × 0.1338 = 0.669 hectares.
Why does the bigha unit differ from state to state?
Bigha is a traditional, pre-metric land unit that was never standardized at the national level. Different regions defined their own bigha sizes based on local practices, and many state governments later codified these local values for official land records. That's why a bigha in Assam and a bigha in Bihar are two completely different areas.
Are Assam land records in bigha or hectare?
Assam land records (Jamabandi/patta) typically record area in bigha, katha, and lecha. However, government reports, agricultural surveys, and central government schemes often use hectares. Both units are in active use depending on the context.
How do I convert 2.5 hectare to bigha in Assam?
Multiply 2.5 by 7.4759: 2.5 × 7.4759 = 18.69 bigha.
Whether you're a farmer cross-checking your PM-KISAN land details, a buyer verifying a seller's claim, or someone simply trying to make sense of a land document, knowing that 1 hectare equals 7.4759 bigha in Assam is the one fact that makes everything else fall into place. Keep the conversion table handy, always confirm which bigha standard is being used, and when in doubt, check with the local revenue office or a certified land surveyor before finalizing any transaction.
