Land measurement in West Bengal refers to the process of determining the area and boundaries of a parcel of land using recognised units. Traditional units such as Bigha, Katha, and Chhatak are still used alongside standard units such as Acre, Decimal, Square Feet, and Square Metre. The West Bengal registration system itself provides land-area fields for Acre, Decimal, Bigha, Katha, Chhatak, and Square Feet when assessing land value.

To convert a land measurement, first identify the unit in the property document, then apply the relevant conversion factor.

For example, to convert 5 Katha into square feet:

5 × 720 = 3,600 sq ft

Similarly, to convert 2 acres into square feet:

2 × 43,560 = 87,120 sq ft

Using a consistent conversion factor helps avoid errors when comparing property documents or estimating land value.

The commonly used land measurement units and their approximate relationships are:

1. Bigha: Bigha is a traditional unit used to measure relatively large land parcels. In the West Bengal standard cited by the state's registration department, 1 Bigha is approximately 14,400 square feet and is divided into 20 Katha.
2. Katha: Katha is commonly used for residential and other land parcels. In the West Bengal standard, 1 Katha equals approximately 720 square feet or 16 Chhatak.
3. Chhatak: Chhatak, also written as Chatak or Chitak in some contexts, is a smaller traditional unit. The West Bengal registration department lists 1 Chhatak as approximately 45 square feet.
4. Decimal: Decimal is widely used for describing smaller land parcels, particularly in eastern India. One Decimal represents 1/100th of an Acre, equivalent to approximately 435.6 square feet.
5. Acre: An acre is a standard unit used to measure larger agricultural and land parcels. One Acre equals 43,560 square feet and 100 Decimal.
6. Square feet and square metres: Square feet and square metres are standard units commonly used in property transactions, construction, valuation, and official documentation. They also make it easier to compare land measurements expressed in traditional units.
 

Accurate measurement can help:

• Verify the actual size of a property.
• Reduce boundary-related disputes.
• Support property valuation.
• Facilitate property registration.
• Compare sale prices accurately.
• Verify land records.
• Assist with construction planning.
• Support property-related financing.
• Improve transparency during property transactions.

Understanding land measurement in West Bengal is important for buyers, sellers, farmers, developers, and property investors. Traditional units such as Bigha, Katha, Chhatak, and Decimal are still used alongside Acre, Square Feet, and Square Metre. Knowing their relationships can make property valuation, documentation, registration, and verification easier. Since land records and applicable measurements should be verified against official sources, buyers should check the relevant government records before completing a property transaction.
