Learn how to convert Katha to square feet accurately based on regional measurement standards across India.
Last updated on: February 16, 2026
Katha or kattha is a traditional land measurement unit widely used in states like Bihar, Jharkhand, and West Bengal. However, most legal land documents, construction plans, property listings, and home loan providers rely on standard units like square feet to determine property value.
Converting between these units helps eliminate confusion and ensures accurate calculations when dealing with land measurements. Since katha to sq ft conversion values can vary by region, understanding the correct katha into square feet measurement provides clarity when buying, selling, or developing land and helps in making informed decisions.
Knowing how to convert katha into square feet is important for ensuring accuracy and credibility of your assets:
Legal compliance: Even if local measures are common, the legal real estate domain still requires the use of the same metrics for deeds. Accurate conversion eliminates conflicts during the process of registration and makes your documents legally valid.
Global standardisation: As regional land measurement units lack uniformity. By converting you allow your property dimensions to be easily understandable worldwide, thereby easing the property transactions.
Precise valuation: Property prices are generally determined by the area in square feet. Therefore, if you are aware of the exact area that 1 kattha in square feet occupies, you will be able to find out the correct property value, which will save you from losing out on negotiations.
Financial assessment: Banks and lenders need accurate size in square feet for the precise property value which is done before granting the mortgage or doing home loan interest rate comparison.
Katha is a traditional unit of land measurement predominantly used in parts of India, particularly in states like Bihar, Jharkhand, Assam, and West Bengal. Its usage dates back to historical times when local systems of measurement were more prevalent than standardised units. The size of a Katha varies significantly across regions, making it a non-standardised unit.
For example, 1 Kattha in square feet in West Bengal is generally equal to 720 square feet, while in other states, the value may differ. Despite these variations, Katha remains widely recognised in rural and semi-urban areas for measuring agricultural or residential land. Understanding its regional significance is crucial for land transactions and ensuring clarity in property-related dealings.
The evolution of Katha is strongly connected with the farming culture of the Indian subcontinent, dating back to the Vedic and Mauryan periods. It was the primary land area measurement unit in eastern India, Nepal and Bangladesh, which were then under Pala Empire (8th-11th centuries AD). Katha was derived as a sub-unit of Bigha, another traditional unit of measure.
Going back to the Vedic and Mauryan periods, it served as a main land measuring unit in eastern India, Nepal, and Bangladesh, which can be traced back to the Pala Empire (8th–11th centuries AD). Katha was derived as a sub-unit of Bigha, another traditional measure.
While it predates British rule, the unit was formalised during the colonial era for land revenue systems across Bihar, West Bengal, and Uttar Pradesh. Even after the mid-20th-century transition to the metric system, Katha was still in use in the local records, but its size varied vastly from one region to the other. For example, 1 Kattha in square feet in Jharkhand is standardised at 1,742 sq ft, whereas in Assam, it can be as large as 2,880 sq ft.

Square Feet (abbreviated as sqft) is a standard unit of area measurement used to quantify the size of land, rooms, and buildings. It represents the area covered by a square with each side measuring one foot. Unlike the International System of Units (SI) which uses meters, this Imperial unit is the dominant standard in the real estate sectors of India, the US, and Canada. .
For example, when buying a plot, you might need to convert square feet to katha to verify local limits. In India, this unit is part of the measurement and is recognised globally, making it a convenient standard for property dealings and space calculations.
The square foot, a unit of area in the imperial and US customary systems, equates to exactly 144 square inches. Its roots lie in ancient civilisations like Egypt and Rome, where linear dimensions were originally based on human anatomy, typically the length of an average adult male foot.
Standardisation was formalised in medieval England in 1303, when King Edward I defined the inch using barleycorns, fixing the foot at 12 inches to ensure consistency in trade. Today, despite the rise of the metric system, the square foot (sqft) persists as the primary standard for real estate in the US, India, and Canada. This historical stability is why modern home loan providers continue to use it as the benchmark for valuing property and calculating asset worth.

Katha is larger than Square Feet. For instance, 1 Katha in square feet in UP is equal to 1361 Square Feet.
In Central India, common land measurement units include Hectares, Acres, Bigha, and Square Feet, depending on the context and locality.
One katha in square feet is equivalent to 720 ft in West Bengal. However, this value varies based on the region.
The number of Katha in Square Feet depends on the regional conversion factor. The number of Katha in Square Feet depends on the regional conversion factor. For example, in West Bengal, 2 Katha in square feet is equal to 1,440 sqft, while in Bihar, the value for the same measurement would differ significantly.
Listings show different sizes because Katha is a local unit that lacks a fixed national standard. Hence, the actual land area it represents fluctuates significantly based on the specific measuring customs followed in different districts or states.
Square feet can be converted to Katha by dividing the area in square feet by the conversion figure of Katha in your area. The formula will be as follows: Area in Katha = Total Square Feet ÷ Value of 1 Katha
While modern government land records (RoR) primarily use Hectares or Square Meters for legal standardisation, traditional deeds and local revenue records in eastern India still frequently document land areas in Katha and Bigha.
