Bigha to Hectare Conversion: Formula & State-Wise Guide

If you have ever looked at a land record, sale deed or property document in India, you may have come across land area mentioned in bigha. Since the value of a bigha is not the same across the country, you may need to convert it into hectares to understand the area in a standard unit. This guide explains what a bigha and a hectare are, shows you the formula for converting one to the other, and provides state-wise conversion values to help you calculate your plot's area.

What is a Bigha?

A bigha is a traditional unit of land measurement used in India and some neighbouring countries. It is particularly common in discussions around agricultural land, rural property and land records. Bigha does not represent a fixed area throughout the country. Its size has developed through different regional land-measurement practices, which means that one bigha in Rajasthan may cover a different area from one bigha in Assam, Haryana or another state.

The Government of India’s metadata standards for land records include bigha, biswa, biswansi, kanal, marla and several other traditional units. The same document provides region-specific conversion factors, illustrating why a single national value for bigha cannot be used reliably. For instance, it records different bigha measurements for Rajasthan and Assam.

What is a Hectare?

A hectare is a metric unit of area commonly used to measure land. Unlike bigha, it has a standard value regardless of where the land is located. One hectare is equal to 10,000 square metres, making it a convenient unit for measuring agricultural land, large plots and other sizeable areas.

A hectare is also equivalent to approximately 2.471 acres. Because it follows the metric system, it provides a consistent way of comparing land areas across different states and countries. This makes hectare particularly useful when land records, government statistics or property information need to be expressed in a standard unit.

Bigha to Hectare Conversion Formula

The method is simple, and it is the same in every state. Only the value of one bigha changes.

If you only know the value of a bigha in square metres, you can use a two-step method instead:

1. Multiply the number of bigha by the value of 1 bigha in square metres.

2. Divide the result by 10,000 to get hectares.

To go the other way, from hectares back to bigha, divide the number of hectares by the value of 1 bigha in hectares.

State-Wise Bigha to Hectare Conversion

The value of a bigha varies across India, and some states have more than one local measurement system. The following table lists the states and regional systems for which a government source provides a bigha-to-hectare conversion:

Source: Government of India's state-wise conversion tables and land-record measurement standards. Values may vary where more than one local bigha system is in use.

For the remaining states, bigha is not listed as the applicable local land-measurement unit in the government conversion table used above. 

These states may instead use units such as acres, cents, decimals, guntha, kanal or hectares. If a property document in one of these states still mentions bigha, you should check the applicable local land records or revenue authority rather than applying a conversion from another state. This is because there is no single India-wide value for a bigha.

Why Does Bigha Vary From State to State?

Bigha is a traditional land measurement that developed before India adopted the metric system as the standard for measuring land. Different regions developed their own ways of measuring and recording land, so the size represented by one bigha was not uniform across the country.

This variation continued as states maintained their own land-record and revenue systems. As a result, the same term, bigha, can represent different areas in different regions. In some places, there can even be more than one accepted bigha measurement within the same state.

For example, government land-record standards identify different bigha systems in Rajasthan, while state-wise conversion tables provide different values for bigha in states such as Assam, Haryana, Himachal Pradesh, Uttar Pradesh and Uttarakhand. This is why you should always check the state and applicable local measurement system before converting bigha into hectares.

Today, hectare provides a standard metric measure, which makes it easier to compare land areas across different regions. However, when a property is recorded in bigha, the correct local conversion must be used rather than applying a single nationwide value.

Bigha to Hectare Conversion: Things to Keep in Mind

Before converting bigha to hectares, make sure you are using the right regional measurement. A small difference in the conversion factor can change the calculated area, especially when dealing with a large plot or a property transaction. Keep these points in mind:

• Check The State: The value of a bigha varies across states and, in some cases, between local measurement systems.

• Verify The Unit: Check the land record or sale deed to confirm that the area is actually recorded in bigha and identify the applicable local system.

• Use Official Records: For property purchases, valuations or loan applications, rely on official land records and documents rather than a generic online conversion.

• Check Local Variations: Some states have more than one bigha measurement. Rajasthan, for example, has different documented bigha systems with different hectare equivalents.

• Avoid Generic Conversions: Do not assume that 1 bigha has the same hectare value everywhere in India.

• Confirm Before Applying: If you are using the converted area for a property purchase or home loan, cross-check the figure with the relevant property documents before proceeding.

Secure Funding for Your Home

Knowing the exact size of a plot matters most when you are about to put money into it. Whether you are buying land to build on, or planning to construct a house on a plot you already own, the area on your documents will be checked and compared with what a lender or a valuer sees. A clear conversion from bigha to hectare, backed by the official record, helps keep that process smooth and avoids delays caused by mismatched figures.
