Understanding Katha to Square Feet Conversion
Katha is a traditional unit of land measurement widely used in parts of India, Nepal, and Bangladesh. Its size varies significantly by region, making accurate conversion essential for property transactions, land valuation, and construction planning. This converter provides a reliable method to translate Katha measurements into square feet, the standard unit used in most real estate documentation.
Regional Variations of Katha
The value of one Katha is not uniform across all regions. Understanding the specific regional standard is critical for accurate conversion.
| Region | 1 Katha (in Square Feet) | Common Use |
|---|---|---|
| West Bengal (India) | 720 sq ft | Urban and rural land records |
| Bihar (India) | 1,361.25 sq ft | Agricultural and residential plots |
| Assam (India) | 2,880 sq ft | Tea estates and rural holdings |
| Nepal | 3,645 sq ft | Land registration and property deeds |
| Bangladesh | 720 sq ft | Standard land measurement |
How the Conversion Works
The converter applies a simple multiplication formula based on the selected regional standard. The core calculation is:
Square Feet = Number of Katha × Regional Conversion Factor
For example, if you select the West Bengal standard and enter 5 Katha, the calculation is 5 × 720 = 3,600 square feet. The tool automatically applies the correct factor based on your region selection.
How to Use the Converter
- Select the region that matches your land's jurisdiction. This determines the correct conversion factor.
- Enter the Katha value in the input field. You can use decimal values for partial Katha measurements.
- View the result displayed instantly in square feet. The output updates as you adjust the input.
Practical Applications
This conversion is commonly needed in several real-world scenarios:
- Property purchase and sale: Comparing land sizes listed in different units across regional markets.
- Construction planning: Calculating buildable area when architectural plans use square feet but land records use Katha.
- Legal documentation: Preparing accurate measurements for sale deeds, mutation records, and land registration.
- Agricultural planning: Determining crop area and input requirements for farming operations.
Common Mistakes to Avoid
- Using the wrong regional factor: Applying the West Bengal standard to a property in Bihar will produce a significant error. Always verify the local standard.
- Confusing Katha with other units: Katha is sometimes confused with Bigha or Decimal. Ensure you are converting the correct unit.
- Rounding prematurely: For large land parcels, rounding intermediate values can compound errors. Use precise decimal values when entering measurements.
Limitations and Precision Notes
While this converter provides accurate results based on standard regional factors, users should be aware of certain limitations:
- Some localities may use slightly different conversion factors than the standard regional values. Always cross-reference with local land records.
- The converter assumes standard definitions. Historical land records may use older or non-standard conversion factors.
- For legal transactions, always verify conversions with a licensed surveyor or local land authority.

There is no single standard size. The most common values are 720 sq ft (West Bengal, Bangladesh), 1,361.25 sq ft (Bihar), 2,880 sq ft (Assam), and 3,645 sq ft (Nepal). Always confirm the regional standard applicable to your property.
Can I convert decimal Katha values?
Yes, the converter accepts decimal values. For example, 2.5 Katha in West Bengal equals 1,800 square feet (2.5 × 720). This is useful for irregularly sized plots.
Is this converter suitable for legal documentation?
This tool provides a reliable estimate for planning and comparison purposes. For legal documents such as sale deeds or land registration, you should obtain certified measurements from a government-approved surveyor.
How does Katha relate to other land measurement units?
In many regions, 20 Katha equals 1 Bigha. However, this relationship also varies by location. For example, in West Bengal, 1 Bigha equals approximately 14,400 sq ft (20 Katha × 720 sq ft).
Why does the same Katha value give different square foot results?
Because the conversion factor changes by region. A 10 Katha plot in West Bengal equals 7,200 sq ft, while the same 10 Katha in Assam equals 28,800 sq ft. Always select the correct region to get an accurate result.
