Free Katha to Square Feet Converter

Understanding the Katha Unit and Its Regional Variations

The Katha is a traditional unit of land area that remains in widespread use across South Asia, particularly in Bangladesh, Nepal, and several states in Eastern India such as Bihar, Assam, and West Bengal. Despite the adoption of the metric system, the katha continues to be the preferred measure for land transactions and rural property descriptions. However, one of its most challenging characteristics is the lack of a universal standard: the size of a single katha can differ substantially from one region to another. For instance, a katha in Bangladesh equals 720 sq ft, while in Nepal the same unit represents 3,645 sq ft. Similarly, within India, states like Bihar and West Bengal have their own variations. This converter is designed specifically to handle these regional differences, enabling you to accurately convert Katha to Square Feet based on the location you select.

Katha to Square Feet Conversion Reference

The table below lists the equivalent area in square feet for one katha in various regions. Choose the row that corresponds to your location to perform precise conversions.

Region	1 Katha (sq ft)
Bangladesh	720
Nepal	3,645
Gorakhpur	1,361
Patna	1,361
Bihar (general)	750 – 2,000 (varies)
South Bihar	1,361
Saran	1,742.24
Aurangabad	1,361.25
Gaya	1,361.25
Assam	2,880
West Bengal	720

To use this data for conversion, simply multiply the number of katha by the factor corresponding to your region. For example:

$$\text{Area (sq ft)} = \text{Katha} \times \text{Regional Value}$$

So, for 5 katha in Assam (where 1 katha = 2,880 sq ft), the result would be:

$$5 \times 2{,}880 = 14{,}400 \text{ ft}^2$$

Converting Square Feet Back to Katha

If you have an area measured in square feet and need to express it in katha, the same regional factors apply in reverse. The table below shows how many katha are contained in 10,000 square feet for each region.

Region	10,000 sq ft (katha)
Bangladesh	13.88889
Nepal	2.74348
Gorakhpur	7.34754
Patna	7.34754
Bihar (general)	varies (5 to 13.333)
South Bihar	7.34754
Saran	5.73974
Aurangabad	7.34619
Gaya	7.34619
Assam	3.47222
West Bengal	13.88889

To convert any given area in square feet to katha, use the formula:

$$\text{Katha} = \dfrac{\text{Area (sq ft)}}{\text{Regional Value (sq ft per katha)}}$$

For instance, a 5,000 sq ft plot in Nepal (where 1 katha = 3,645 sq ft) would be:

$$\dfrac{5{,}000}{3{,}645} \approx 1.371 \text{ katha}$$
