Bigha to Acre Calculator

If you have ever tried to buy or sell agricultural property, or even understand a property listing in India, you have probably heard the words acre and Bigha.

The same piece of land gets described in acres in one document and bighas in another. And if you are from Bihar, the bigha value is completely different from what someone in Punjab or West Bengal would tell you.

In this detailed article, we will clear all that confusion. You will learn what an acre is, what a Bigha is, the difference between them, how to convert an acre to a Bigha, and popular acre-to-Bigha conversions. So, let us start this blog.

What is an Acre?

An acre is one of the oldest and most widely used units of land measurement in the world. The word comes from the Old English word 'æcer', which simply meant an open field.

Historically, an acre was defined as the amount of land a man with a pair of oxen could plough in a single day. Over centuries, this got standardised, and today:

1 Acre = 43,560 square feet (or about 4,047 square metres, or roughly 4,840 square yards)

To make it more visual: a standard football field in India is roughly 1.32 acres in size. So if you can picture that, you have a good idea of what 1 acre looks like on the ground.

Acre is used widely in Punjab, Haryana, Himachal Pradesh, Delhi NCR, Karnataka, Maharashtra, and Rajasthan. It is also the preferred unit in international real estate, US and UK property records, and across most British Commonwealth countries.

Dimension of Acre

1 Acre	43,560 square feet
1 Acre	4,840 sq yd
1 Acre	0.4047 hectares
1 Acre	4,047 sq m
1 Acre	1/640th of a square mile

What is a Bigha?

Bigha is also written as Beegha. It is a traditional Indian unit of land measurement. Bigha has been used across North India, East India, Nepal, and Bangladesh for hundreds of years.

But Bigha has no single fixed. Unlike acres, bigha was never standardised at a national level. Different kingdoms, regions, and communities developed their own versions, and those local definitions have stayed in use right up to today.

There are two main types of Bigha:

Pucca Bigha (also called Pakka Bigha) – It is the larger version, more commonly used version in official property dealings
Kaccha Bigha – It is a smaller version, still used in some rural areas, especially for tenancy agreements

The size of 1 bigha ranges from about 6,804 sq ft (in hilly parts of Uttarakhand) to 27,225 sq ft (in Rajasthan or Haryana). This is a massive difference nearly four times which is why knowing your state's bigha value before any transaction is absolutely essential.

Bigha is most commonly used in Uttar Pradesh, Bihar, Jharkhand, West Bengal, Assam, Rajasthan, Punjab, Haryana, Himachal Pradesh, Uttarakhand, Madhya Pradesh, and parts of Gujarat.

Acre to Bigha: The Basic Formula

The general formula for converting acres to bigha is straightforward:

Acre to Bigha Bigha = Acre × Regional Conversion Factor

Bigha to Acre Acre = Bigha ÷ Regional Conversion Factor

The standard approximate value used across most of India is:

1 Acre = 1.613 Bigha (general standard)

For example, if you want to convert 2 acres to bigha, then you must multiply 2 by 1.613. Therefore 2 acres = 2 × 1.613 = 3.226 bigha. Similarly:

50 acres = 50 × 1.613 = 80.65
30 acres = 30 × 1.613 = 48.39

But this is just an average. In reality, your state's specific conversion factor matters much more. See the state-wise table below for accurate numbers.

State-Wise Acre to Bigha Conversion Table

This is the most important table in this guide. Because bigha varies by state, always use the value specific to where your land is located.

State	1 Bigha (Sq Ft)	1 Acre = ? Bigha	1 Bigha = ? Acre
Uttar Pradesh (West)	27,000	1.61	0.62
Bihar	27,220	1.60	0.625
Rajasthan (Pucca)	27,225	1.60	0.625
West Bengal	14,400	3.025	0.33
Assam	14,400	3.025	0.33
Punjab	9,070	4.80	0.208
Haryana	9,070	4.80	0.208
Himachal Pradesh	8,712	5.00	0.20
Uttarakhand (Hills)	6,804	6.40	0.156
Madhya Pradesh	12,000	3.63	0.275
Gujarat	17,424	2.50	0.40
Rajasthan (Kachha)	17,424	2.50	0.40
Jharkhand	27,220	1.60	0.625
Odisha	14,400	3.025	0.33

Note: Some states like Tamil Nadu, Karnataka, Kerala, Andhra Pradesh, and Telangana do not traditionally use the bigha unit. These states have their own measurement systems such as Cent, Guntha, Ground, and Ankanam.

For other values, use the formula: Bigha = Acres × your state factor

How to Convert Acre to Bigha — Step by Step Examples

Example 1: Converting 5 Acres in Uttar Pradesh
State: UP (West) | 1 Acre = 1.60 Bigha
5 Acres × 1.60 = 8 Bigha
So, 5 acres of land in western UP equals 8 bighas.

Example 2: Converting 3 Acres in West Bengal
State: West Bengal | 1 Acre = 3.025 Bigha
3 Acres × 3.025 = 9.075 Bigha
In West Bengal, 3 acres equals slightly more than 9 bighas.

Example 3: Converting 10 Acres in Punjab
State: Punjab | 1 Acre = 4.80 Bigha
10 Acres × 4.80 = 48 Bigha
This shows just how different Punjab's bigha is. 10 acres = 48 bighas here, while in UP it would be only 16 bighas.

Example 4: Converting 2 Acres in Bihar
State: Bihar | 1 Acre = 1.60 Bigha
2 Acres × 1.60 = 3.20 Bigha
Bihar follows a standard similar to UP - straightforward and easy to calculate.

Other Important Land Measurement Units Related to Bigha

Bigha does not exist in isolation. It is connected to many other traditional units that you will see in property documents across India.

Unit	Equal To	Common States
1 Biswa	1/20th of a Bigha	UP, Uttarakhand
1 Katha	1/20th of a Bigha (Bengal)	West Bengal, Bihar
1 Marla	272.25 sq ft	Punjab, Haryana
1 Kanal	5,445 sq ft (1/8 acre)	Punjab, Haryana, J&K
1 Gunta/Guntha	1,089 sq ft	Maharashtra, Karnataka
1 Cent	435.6 sq ft (1/100 acre)	South India
1 Hectare	10,000 sq mt / 2.47 acres	Pan-India (official)

Understanding these sub-units is important because property documents especially older sale deeds and revenue records often mention them. For instance, a deed might say '2 bigha 10 biswa' and you need to convert that correctly.

Why Does Bigha Vary So Much Across India?

This question is very famous, and many people ask, and it has a fascinating historical answer. India was never a single unified country with one ruler for most of its history. Different kingdoms, empires, zamindars (landlords), and colonial administrators all governed different regions.

Each developed its own system of weights and measurements, including land measurement. These local systems got embedded in revenue records, land deeds, and community practice over centuries.

When the British came, they introduced the standardised acre for official land revenue collection, but local units like bigha remained in everyday use among farmers and villagers. After independence, India adopted metric units (hectare, square metre) for official records, but in practice, most people in rural areas still think and transact in bighas.

Common Mistakes People Make in Acre to Bigha Conversions

Using the generic '1 acre = 1.613 bigha' value without checking the state-specific rate
Most people confused between Pucca and Kaccha bigha, you should always ask which one is being used
Not verifying bigha size at the district or village level (some areas differ even within a state)
Trusting verbal descriptions of land area without cross-checking with official records
Using outdated conversion charts that may not reflect current local practices
Not consulting a Patwari or revenue official for large transactions

Acre to Bigha: How Official Records Work in India

In India, land records are maintained at the state level, primarily through the Revenue Department. The key documents you will encounter include:

Khasra / Khatauni

These are village-level land records that show who owns what land, in what area, and under what category of use. The area is usually mentioned in local units like bigha, but should also have metric equivalents.

Jamabandi

Used mainly in Punjab, Haryana, Himachal Pradesh, and Rajasthan, Jamabandi is a consolidated record of land ownership and cultivation rights.

Patta

A Patta is a land title document issued by the state government, especially for rural land. It shows the officially recognized area in the applicable local unit.

Note: Most Indian states have now digitized their land records. You can check your state's official portal, like Bhulekh (UP, Bihar), Dharitree (Assam), Bhu-Naksha (Rajasthan), etc., to verify the exact area of any land parcel.

Bigha in Nepal and Bangladesh

Did you know? Bigha is also used in Nepal and Bangladesh, but with different values:

In Nepal: 1 Bigha = 6,773 square metres ≈ 1.67 Acres
In Bangladesh: 1 Bigha = 1,600 square yards ≈ 0.33 Acres (similar to West Bengal)

If you are involved in cross-border land dealings or have ancestral land across these borders, make sure you use the correct country-specific values.
