Biswa to Gaj Conversion: Formula and Examples

In summary

To convert biswa to gaj, multiply the number of biswa by the applicable state- or region-specific conversion factor. Since the value of biswa varies across India, use the factor followed in the relevant land records or local property convention.

• 1 biswa can equal different numbers of gaj depending on the state or local convention
• Formula: gaj = biswa × applicable conversion factor
• Biswa is used for land and property measurement in areas where this traditional unit applies
• Gaj is used for plot and property measurement in areas where this unit applies
• The conversion expresses the same physical land area in another unit

For property comparisons or formal documents, use the same conversion consistently and compare the result with the area stated in the relevant plan, sale deed or registered property record.

To convert biswa to gaj, multiply the area in biswa by the conversion factor applicable to the relevant state or region. Because biswa has different local values, you should identify the applicable convention before calculating.

Formula: Gaj = Biswa × applicable conversion factor

For example, under one commonly used Uttar Pradesh land-measurement convention: 1 biswa = 151.25 gaj

Therefore: 5 biswa × 151.25 = 756.25 gaj

So, under this convention, 5 biswa = 756.25 gaj.

This value should not be applied automatically to properties in other states because the size represented by one biswa can differ by location.

To convert gaj back to biswa, divide the area in gaj by the conversion factor applicable to the relevant state or region.

Formula: Biswa = Gaj ÷ applicable conversion factor

Using the Uttar Pradesh example: 605 gaj ÷ 151.25 = 4 biswa

Therefore, under this convention: 605 gaj = 4 biswa

For a property in another state, use the locally applicable biswa-to-gaj factor before performing the reverse calculation.

An area conversion calculator can help perform the arithmetic after you identify the applicable biswa-to-gaj conversion factor.

For example in Uttar Pradesh, if the applicable factor is 1 biswa = 151.25 gaj:

1. Select biswa as the starting unit.
2. Select gaj as the target unit.
3. Enter the land area.
4. Apply the applicable regional conversion factor.
5. Review the converted area.

For a formal property transaction, compare the converted figure with the area stated in the relevant sale deed, land record, plan or registered property document.

Use biswa when the local property description, land record or discussion uses that unit. Use gaj when the plot or property area is expressed in gaj or when you need to compare areas using square-yard-based measurement. The practical distinction is that biswa can represent different areas depending on the applicable regional convention, while gaj is commonly used as a square-yard measurement.

For example, under the Uttar Pradesh convention used above:

• A local listing may describe a plot as 151.25 gaj
• The physical land area remains the same after conversion

Before using the converted figure in a property transaction, check which biswa convention applies to the property.

Land area can affect property valuation because the size of a property forms part of the information considered when assessing its value. Other factors can include location, property type, permitted use, access, condition and applicable market conditions. A conversion from biswa to gaj does not change the physical size or value of the property. It only expresses the same area using another unit. For valuation or documentation, use the area stated in the applicable property records and ensure that the conversion follows the relevant local convention.

Land measurement can form part of the property information considered when assessing a loan against property application. However, converting biswa to gaj by itself does not determine loan eligibility, sanctioned amount or approval. However, converting biswa to gaj does not determine loan eligibility, the eligible loan amount, or guarantee approval.

A lender separately assesses factors such as:

• Property area and type
• Property location
• Ownership documents
• Legal and technical aspects
• Property valuation
• Income and repayment capacity

If one document records a property in biswa and another uses gaj, converting them correctly can help you check whether both measurements describe the same area before property assessment.

You can compare loan against property interest rates when reviewing potential borrowing costs. You can also use a loan against property EMI calculator to estimate repayments based on the loan amount, interest rate, and tenure. EMI stands for Equated Monthly Instalment.
