Convert Katha to Square Feet

In India, Katha is a traditional land measurement unit commonly used in states such as Bihar, West Bengal, Assam, and parts of Nepal. While widely understood locally, it can create confusion for buyers and investors who rely on standard units like square feet. Since the size of one Katha varies by region, converting Katha to square feet is essential for accurate property valuation, registration, and financial planning.

This conversion plays a critical role in real estate transactions, mortgages, and loan against property applications. Correct measurements help ensure transparent pricing, legally sound documentation, and fair negotiations, reducing the risk of disputes and improving clarity across 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 spelled as kattha or cottah is a traditional land measurement unit and a sub unit of bigha that has been used in India for centuries. Although its use declined after the adoption of the metric system, it is still commonly followed in states such as West Bengal, Bihar, Jharkhand, and Assam. The unit is also prevalent in neighbouring countries like Bangladesh and Nepal.

One important aspect of katha is that it is not standardised. Its area varies significantly by region. For example, one katha equals about 2,880 square feet in Assam, ranges between 750 and 2,000 square feet in Bihar, and measures around 3,645 square feet in Nepal. Due to these variations, converting katha to square feet is widely used in property transactions to ensure clarity and accurate land valuation.

Katha to other conversion units

Katha can also be converted into multiple standard and regional land measurement units. Understanding these conversions helps ensure accuracy in property valuation, registration, and financial or legal transactions across regions.

What is Square Feet?

Square feet, often written as square foot or sq ft and represented as ft², is an imperial unit of area measurement used internationally. It represents the area of a square with each side measuring one foot. This unit is widely followed in countries such as the USA, India, Canada, Singapore, Malaysia, Pakistan, Nepal, Bangladesh, Ghana, and others.

In real estate, square feet is the most commonly used unit to define property size. Residential spaces like apartments are typically measured this way. For example, a 2BHK flat usually ranges between 600 and 900 sq ft, while a 4BHK home can span anywhere from 1,500 to 4,000 sq ft, depending on the layout and location.

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. 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: what applies in Bihar may not hold in Assam or West Bengal. Therefore, while the formula remains the same, the regional multiplier must be used to ensure accuracy.

For example, if you own 3 Kathas in Bihar (1 Katha = 1361 sq. ft.), the total area in square feet is calculated as:

3×1361=4083 sq. ft.

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

Suppose you have 5 Kathas of land in Bihar. To convert it to square feet:

• Identify the regional value: 1 Katha in Bihar = 1,361 sq. ft.
• Multiply the number of Kathas by this value:

5×1,361=6,805 sq. ft.

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

This step-by-step approach ensures clarity, making it easier for property buyers, sellers, and investors to calculate land size accurately. For convenience, an online area conversion calculator can automate this process.
