In summary

  • 1 hectare = 10,000 square metres or approximately 2.47 acres
  • The value of 1 bigha in hectares varies by state and locality
  • Conversion formula: Hectares = Bigha × local hectare value of 1 bigha
  • Always check the applicable local conversion standard before doing property transactions

How to convert Bigha to Hectare?

You can convert bigha to hectare by multiplying the number of bighas by the locally applicable hectare value of one bigha. Since bigha does not have a uniform value across India, the conversion factor should be verified according to the state or district.

Follow these steps to convert bigha to hectare:

  1. Find the land area in bigha.
  2. Identify the locally applicable conversion value of one bigha in hectares.
  3. Multiply the number of bighas by this conversion value.
  4. The result is the land area in hectares.

Formula:

Hectares = Bigha × Hectare value of 1 Bigha


Example:

If 1 bigha is considered equal to 0.25 hectare in a particular region, then:

2 bigha = 2 × 0.25 = 0.50 hectare

Similarly, if the local conversion standard states that 1 bigha equals 0.10 hectare, then:

2 bigha = 2 × 0.10 = 0.20 hectare

Therefore, the same number of bighas can represent different areas depending on the applicable regional standard.

To save time and avoid manual calculations, you can use an area conversion calculator to convert bigha into hectares using the relevant conversion factor.
 

What is Bigha?

Bigha is a traditional unit of land measurement used in several parts of India, particularly in northern and eastern states. However, it is not a standardised unit with one fixed value across the country. Its size can differ significantly between states and even between local areas.

  • Commonly used for measuring agricultural land and large land parcels.
  • The value of one bigha varies across states and regions.
  • Local revenue records should be checked before using bigha for property transactions.
  • A bigha may be converted into hectares using the locally accepted conversion factor.

What is Hectare?

A hectare is a standard metric unit used to measure land area. One hectare equals 10,000 square metres, or approximately 2.47 acres. Unlike bigha, the hectare has a fixed value and does not change according to the region.

  • Commonly used for agricultural land and large property parcels.
  • Used in government land records, surveys and agricultural statistics.
  • One hectare is equal to 10,000 square metres.
  • It is a standardised unit that can be used consistently across regions.

State-wise Bigha to Hectare conversion

The value of bigha differs across India. For example, commonly cited conversion values include approximately 0.25 hectare in Rajasthan and Uttar Pradesh, 0.13 hectare in Assam and West Bengal, 0.16 hectare in Gujarat, 0.10 hectare in Haryana and Punjab, and 0.08 hectare in Himachal Pradesh and Uttarakhand. These values can also vary by local practice.

Converting bigha to hectare helps compare traditional land measurements with a standard metric unit. However, there is no single bigha-to-hectare conversion factor applicable across India. The value of bigha varies by state and locality. Therefore, always confirm the applicable conversion standard from the relevant land records or revenue authority before buying, selling, registering or borrowing funds against land.

Frequently Asked Questions

Overview

Area Conversion

How many hectares are in 1 bigha?

Using the standard conversion, 1 bigha = 0.2529 hectares, based on 1 bigha being equal to 2,529 sq. m. However, bigha is a regionally variable land unit, so the actual hectare equivalent can differ by state or locality. For land transactions, official records and valuations, use the conversion factor prescribed by the applicable state revenue authority.

How many bighas are in 1 hectare?

Using the standard conversion of 1 bigha = 0.2529 hectares, 1 hectare = approximately 3.95 bigha. The reverse calculation is 1 ÷ 0.2529 = approximately 3.95. Since the size of a bigha varies across Indian states, the exact number of bighas in one hectare may differ according to the local land-measurement standard.

How many hectares is 100 bigha?

Using the standard conversion factor, 100 bigha = 25.29 hectares. The calculation is 100 × 0.2529 = 25.29 hectares. This figure is based on 1 bigha = 2,529 sq. m. Because bigha is not a standardised unit throughout India, the actual equivalent can vary where state or local authorities prescribe a different bigha measurement.

Which land measurement units are used in Indian government records?

Indian government land records commonly use hectares, square metres, acres and other locally recognised units, depending on the state and type of record. Traditional units such as bigha, biswa and guntha may also appear in regional records. For official land verification or transactions, the unit and conversion specified by the relevant state revenue or land-records authority should be followed.

Does the government use bigha or hectare for official land records in India?

Government land records in India can use hectares and other metric units as well as traditional regional units such as bigha, depending on the state and record system. Hectare provides a standard metric measurement, while bigha varies geographically. Therefore, when converting or verifying land records, use the unit and conversion factor prescribed by the relevant state revenue authority.

How do I convert smaller bigha subdivisions like biswa to hectares?

To convert a smaller bigha subdivision such as biswa to hectares, first determine how many biswa make one bigha under the applicable local system. Then convert the resulting bigha value into hectares using the state-specific bigha-to-hectare factor. Because both bigha and biswa can vary by region, there is no single nationwide biswa-to-hectare conversion that applies everywhere.

Why does the size of 1 bigha differ across Indian states?

The size of 1 bigha differs across Indian states because bigha is a traditional land-measurement unit rather than a nationally standardised metric unit. Historical practices, regional revenue systems and local measurement conventions have produced different definitions. For example, commonly referenced bigha sizes range from about 1,337 sq. m. to 2,500 sq. m. or more. State-specific records should therefore be used for accurate conversion.

How do surveyors convert bigha to hectare during land verification?

Surveyors generally convert bigha to hectares by first identifying the legally applicable local definition of bigha from revenue records or the relevant authority. They then convert the recorded area into square metres and divide by 10,000 because one hectare equals 10,000 sq. m. The resulting measurement can be checked against the property's survey, cadastral or official land records.

Can I use an online calculator to convert bigha to hectares?

Yes, you can use an online bigha-to-hectare calculator for quick conversions, provided you select the correct state or regional conversion factor. A calculator using a fixed factor such as 0.2529 may not be accurate for every location because bigha varies across India. For legal, valuation or loan documentation, verify the result against official local land records or revenue-authority standards.
