Convert Katha to Square Feet

Katha is a traditional unit of land measurement commonly used in several parts of India, particularly in states such as Bihar, West Bengal, Assam, as well as in neighbouring regions like Nepal. While it is widely understood at a local level, Katha can often create confusion for buyers, sellers, and investors who are more familiar with standard units such as square feet.

Converting Katha to square feet is important because the size of one Katha is not uniform across regions. For example, the area covered by 1 Katha in Bihar differs from that in Assam or West Bengal. This variation directly affects property valuation, registration, and financial transactions, making accurate conversion essential for clarity and consistency.

Understanding Katha to square feet conversion is particularly important in real estate transactions, property registration, and processes such as mortgages or loan against property applications. Correct conversion helps ensure accurate land assessment, fair pricing, and legally sound documentation, reducing the risk of disputes and promoting transparency in property dealings.

Why converting Katha to Square Feet is important?

Here’s why converting katha to square feet is important:

• Standardisation in real estate transactions: Converts traditional land units into universally recognised measurements, improving clarity and consistency across property dealings.
• Easier property valuation: Accurate conversion enables correct market pricing and fair assessment of land value across regions.
• Accuracy for registration and loans: Ensures precise land area documentation during property registration and loan against property applications.
• Helps avoid disputes: Clear conversions minimise confusion and conflicts between buyers, sellers, lenders, and authorities.

What is Katha?

Katha, also known as kattha or cottah, is a traditional unit of land measurement and a sub unit of bigha. It has been used in India for centuries, particularly in northern and eastern regions. Although the metric system has reduced its overall usage, katha continues to be commonly used in states such as West Bengal, Bihar, Jharkhand, and Assam. The unit is also prevalent in countries like Bangladesh and Nepal.

Since katha is not standardised, its measurement varies by location. In Assam, one katha is equal to 2,880 square feet. In Bihar, its size can range between 750 and 2,000 square feet, while in Nepal, one katha measures approximately 3,645 square feet. Because of these variations, converting katha to square feet is widely used in property transactions to ensure clarity, accurate valuation, and proper documentation.

Katha to other conversion units

Converting katha into standard units helps ensure accuracy in land measurement, property valuation, and legal documentation, especially since the size of katha varies across regions.

What is square feet?

Square foot, square feet, or sq ft is a widely recognised imperial unit of area measurement, represented by the symbol ft². It refers to the area of a square with each side measuring one foot. This unit is commonly used across countries such as the United States, parts of Canada, Hong Kong, Singapore, India, Malaysia, Pakistan, Nepal, Myanmar, Bangladesh, and a few others.

Square feet is one of the most commonly used units in real estate. Property sizes for apartments, houses, and commercial spaces are typically mentioned in square feet. For example, a 2 BHK apartment usually ranges between 600 and 900 square feet, while a 4 BHK apartment may measure anywhere between 1500 and 4000 square feet, depending on the layout and location.

Converting square feet into other standard units helps in comparing land sizes, understanding property dimensions, and completing legal or real estate documentation accurately.

Katha to Square Feet conversion formula

The general formula for converting Katha to square feet is:

Square feet = Number of Kathas × Regional value of 1 Katha in sq. ft.

It is important to note that the value of 1 Katha varies by state. For example, the measurement used in Bihar may differ from that in Assam or West Bengal. While the formula remains the same, the regional value must be applied correctly to ensure accuracy.

For example, if you own 3 Kathas of land in Bihar where 1 Katha equals 1,361 sq. ft., the total area is calculated as: 3 × 1,361 = 4,083 sq. ft.

Step-by-step example of Katha to Square Feet conversion

Suppose you have 5 Kathas of land in Bihar. To convert this into square feet:

• Identify the regional value: 1 Katha in Bihar equals 1,361 sq. ft.

• Multiply the number of Kathas by this value: 5 × 1,361 = 6,805 sq. ft.

• The total land area is therefore 6,805 square feet.

This step-by-step method makes land measurement calculations clearer for property buyers, sellers, and investors. For quicker results, an online area conversion calculator can also be used to automate the process.
