What is a Bigha?

Bigha is a traditional unit of land measurement. It has been used in India for hundreds of years, mainly in the northern and eastern states. Farmers use it to describe how much land they own or cultivate.

The most important thing to know about Bigha is this: it does not have one fixed size. The value of 1 Bigha is different from state to state and sometimes even from one district to another within the same state.

For example:

In Bihar, 1 Bigha = 27,220 square feet
In West Bengal, 1 Bigha = 14,400 square feet
In Punjab, 1 Bigha = 9,070 square feet

This difference causes a lot of confusion. That is why you always need to know which state you are dealing with before doing any Bigha conversion.

The History of Bigha

The word "Bigha" is believed to have come from the Sanskrit word "vigraha", which means division. This unit has been used since ancient times, mainly to measure agricultural land.

During the Mughal period, Bigha became more widely used across the Indian subcontinent. It was used for tax collection and land records. The British later tried to standardize it, but the regional differences were too deeply rooted in local customs. So even today, Bigha means different things in different parts of India.

In West Bengal, for instance, the British standardized Bigha to be one-third of an acre. But in other states, local measurements were kept as they were.

Difference Between Pucca Bigha vs Kachcha Bigha

You may have heard two types of Bigha being mentioned "Pucca Bigha" (also spelled Pakka Bigha) and "Kachcha Bigha." Here is what they mean:

Pucca Bigha (Pakka Bigha): This is the larger and more standardized form of Bigha. It is commonly used in Rajasthan, parts of Uttar Pradesh, Bihar, and Uttarakhand. 1 Pucca Bigha is equal to 27,225 square feet or approximately 0.625 acres.

Kachcha Bigha: This is a smaller, informal measurement. It was historically used by landlords when dealing with tenants in North India. Kachcha Bigha is roughly half or less of a Pucca Bigha. It is less commonly used today.

Pro Tip — Always confirm whether the Bigha being discussed is Pucca or Kachcha, especially in Rajasthan and older land records.

What is an Acre?

An acre is a standard international unit of land measurement. It is used all over the world in India, the United States, the United Kingdom, and many other countries.

1 Acre is equal to 43,560 square feet or approximately 4,047 square meters.

The word "acre" comes from the Old English word "æcer" which means field. Historically, it was the amount of land a yoke of oxen could plow in one day. Today, it is used for measuring agricultural land, real estate, and large plots.

Unlike Bigha, the acre has the same value everywhere in India and the world. This makes it a reliable unit for official transactions, property registration, and legal documents.

Bigha to Acre Formula — How to Calculate

Converting Bigha to Acre depends on your state. Here is the general formula:

Bigha to Acre Acres = Bigha × State-Specific Conversion Factor

Acre to Bigha Bigha = Acre ÷ State-Specific Conversion Factor

Example (Bihar, 1 Bigha = 27,220 sq ft):
1 Bigha = 27,220 ÷ 43,560 = 0.625 Acres
10 Bigha = 10 × 0.625 = 6.25 Acres
100 Bigha = 100 × 0.625 = 62.5 Acres

Example (West Bengal, 1 Bigha = 14,400 sq ft):
1 Bigha = 14,400 ÷ 43,560 = 0.33 Acres
10 Bigha = 10 × 0.33 = 3.3 Acres

Assam	14,400 sq ft	0.33 Acre	3.03 Bigha
Punjab	9,070 sq ft	0.208 Acre	4.80 Bigha
Haryana	9,000 sq ft	0.207 Acre	4.83 Bigha
Madhya Pradesh	12,000 sq ft	0.27 Acre	3.70 Bigha
Gujarat	17,424 sq ft	0.40 Acre	2.50 Bigha
Himachal Pradesh	8,712 sq ft	0.20 Acre	5.00 Bigha
Uttarakhand	6,804 sq ft	0.156 Acre	6.40 Bigha
Jharkhand	27,211 sq ft	0.625 Acre	1.60 Bigha

Note: These are the most commonly accepted standard values. The exact size may vary in some districts. Always confirm with your local Patwari, Tehsildar, or Revenue Office before any legal transaction.

State-by-State Breakdown

Bigha in Uttar Pradesh (UP)

Uttar Pradesh uses Pucca Bigha, which equals 27,000 square feet. This is one of the most common forms of Bigha used across India. In UP, 1 Bigha is approximately 0.62 acres. The local sub-units of Bigha in UP are Biswa (1 Bigha = 20 Biswa) and Biswansi (1 Biswa = 20 Biswansi).

Bigha in Bihar

Bihar uses a very similar value to UP. Here, 1 Bigha = 27,220 square feet = 0.625 acres. Bihar farmers rely heavily on Bigha for agricultural land measurement. This value is also used across Jharkhand, which was carved out of Bihar.

Bigha in West Bengal

West Bengal is different from North India. Here, 1 Bigha = 14,400 square feet = 0.33 acres. So a Bigha in West Bengal is almost half of a Bigha in Bihar. When the British standardized land in Bengal, they fixed 1 Bigha as one-third of an acre. The sub-units in West Bengal are Katha (1 Bigha = 20 Katha) and Chhatak (1 Katha = 16 Chhatak).

Bigha in Rajasthan

Rajasthan mainly uses Pucca Bigha, where 1 Bigha = 27,225 square feet = 0.625 acres. In some areas, Kachcha Bigha (smaller size) may still be referenced in older records. The term Biswa is also common in Rajasthan as a sub-unit.

Bigha in Punjab and Haryana

Punjab and Haryana use a much smaller Bigha. In Punjab, 1 Bigha = 9,070 square feet = 0.208 acres. In Haryana, it is similar at around 9,000 square feet. So 1 Acre in Punjab equals about 4.8 Bigha. Punjab also uses Kanal and Marla as popular sub-units.

Bigha in Assam

Assam follows the same measurement as West Bengal. Here 1 Bigha = 14,400 square feet = 0.33 acres. In Assam, the sub-unit is Katha (1 Bigha = 5 Katha in Assam).

Bigha in Madhya Pradesh

In Madhya Pradesh, 1 Bigha = 12,000 square feet = 0.27 acres. This makes it notably smaller than the UP or Bihar standard. Local land records in MP will often mention Bigha alongside other units like Guntha.

Bigha in Gujarat

Gujarat's Bigha is mid-sized at 17,424 square feet = 0.40 acres. In some parts of Gujarat, Vigha is the local name for Bigha. 1 Acre in Gujarat equals approximately 2.5 Bigha.

Bigha in Himachal Pradesh and Uttarakhand

These hill states have the smallest Bigha values in India. In Himachal Pradesh, 1 Bigha = approximately 8,712 sq ft. In Uttarakhand, especially in hilly areas, it can be as small as 6,804 sq ft. This means 1 Acre can equal 5 to 6.4 Bigha in these states.

Practical Tips for Land Buyers and Sellers

Buying or selling land in India can be complicated, especially when different units are being used. Here are some practical tips to help you:

Always ask in which unit the land is being measured. Different sellers may use different units.
Confirm the state-specific Bigha value before doing any calculation. A Bigha in UP is twice the size of a Bigha in West Bengal.
If in doubt, ask the local Patwari or Tehsildar. They have the official records and can give you the correct measurement.
When applying for a home loan or mortgage, the bank will usually require the land area in square meters or square yards. Make sure you have the conversion ready.
For agricultural loans under PM Kisan or other schemes, land is often declared in Bigha locally but converted to hectares for official records.
Always cross-check land measurements with the registered land documents (Khasra, Khatauni, or Patta).
Online land conversion calculators can help, but always verify the result with the official state-specific factor.

Bigha and Other Land Units

Bigha is part of a larger family of traditional Indian land units. Here is how they relate to each other (using Bihar/UP Pucca Bigha as the base):

1 Bigha = 20 Biswa
1 Biswa = 20 Biswansi
1 Bigha = 0.625 Acres
1 Bigha = 0.253 Hectares
1 Bigha = 27,220 Square Feet
1 Bigha = 3,024 Square Yards (Gaj)
1 Bigha = 2,529 Square Meters

These sub-units vary too. For example, in West Bengal, 1 Bigha = 20 Katha, while in Assam, 1 Bigha = 5 Katha. So when dealing with sub-units, the same caution about regional variation applies.

Why Does Bigha Vary Across States?

You might be wondering, why is there no standard Bigha in India? The answer lies in history. Before British rule, different kingdoms and regions had their own ways of measuring land. The Mughal administration used Bigha, but different provinces interpreted the measurement differently based on local customs and land use.

During colonial rule, the British tried to standardize land measurement for tax collection. They succeeded in some regions (like Bengal) but not everywhere. Many states kept their local Bigha values in their revenue records.

After independence, India adopted the metric system for most official purposes. But in rural areas, people continued using Bigha because it was familiar. The metric system is used in official documents, but Bigha remains the everyday language of land across North India.

Today, states like Himachal Pradesh and Uttarakhand have the smallest Bigha (because their hilly terrain meant smaller plots were farmed), while states like Bihar, UP, and Rajasthan have the larger Pucca Bigha.

Conclusion

If you want to buy, sell, or invest in land in India, it is important to understand the Bigha-to-Acre conversion. The value of a bigha varies from state to state, and many people often get confused while calculating land area.

But on the other hand, an acre is a standard unit that remains the same everywhere. Converting Bigha to Acres makes land measurements easier to understand for legal paperwork, property registration, bank loans, and real estate transactions.

Whether you are a farmer, landowner, investor, or first-time buyer, having proper knowledge of land conversion can save you time, money, and future disputes.
