In India, land measurement plays a crucial role in agriculture, real estate, and urban planning. Among the various units of land measurement, acre to katha conversion is particularly important. While an acre is a globally recognized standard, katha is a traditional unit commonly used in states like West Bengal, Bihar, Assam, and Odisha. Understanding these units and how to convert between them is essential for anyone involved in property transactions, farming, or managing real estate. Accurate conversions help ensure transparency and clarity when dealing with land measurements across different regions of the country.

For those looking to leverage the value of their property, knowing the correct land measurement is also critical when considering a loan against property. Lenders typically require accurate land valuations to assess the loan amount, and understanding units like acre and katha can help ensure that you receive a fair loan offer based on your property’s actual size. Whether you're involved in real estate transactions or seeking financial assistance, having a clear understanding of land measurements is key to making informed decisions.

Read on to understand the concept of acre and katha, the conversion between them, and why it matters in India’s diverse land measurement system.

What is an acre?

An acre is a standard unit of area measurement widely used in India, especially for larger land areas like agricultural fields, estates, and even real estate. In India,1 acre is equivalent to 43,560 square feet or roughly 4,047 square meters.
The acre is part of the imperial measurement system, which is commonly used in countries like India, the United States, and the UK. The unit is mostly used for measuring larger plots of land, especially in rural areas where agriculture plays a major role in the economy. Whether you are looking at farmland, large properties, or rural plots, the acre serves as a standard measurement that helps simplify land transactions and ownership.

History of acre

The acre has a long history as a unit of land measurement, dating back to the Middle Ages in England. Originally, an acre represented the amount of land that could be ploughed by a yoke of oxen in one day. The term derives from the Old English word “æcer,” meaning open field. Its size varied across regions until it was standardized in 1878 by the British Weights and Measures Act as 4,840 square yards or 43,560 square feet. Today, the acre is widely used in countries like the United States, Canada, and parts of South Asia for measuring land area.

What is a katha?

A katha is a traditional land measurement unit used in several states across India. The term is most commonly used in Bihar, West Bengal, Assam, and parts of Uttar Pradesh. Unlike the acre, the size of a katha can vary by region. In many places,1 katha is generally considered to be1,360 square feet, but it can range from1,200 square feet to 1,800 square feet depending on the state. The katha is often used for measuring smaller plots of land, particularly in semi-urban and rural areas where land sizes are smaller compared to agricultural fields. It is also commonly used in real estate transactions in urban or suburban regions.

History of katha

Katha is a traditional unit of land measurement widely used in eastern India, particularly in states like Bihar, West Bengal, Assam, and Jharkhand. Its origin dates back to ancient and medieval times when land was measured based on local practices rather than standardised systems. The size of a katha varies from region to region, reflecting cultural and administrative differences across territories. For instance, one katha equals 1,361 square feet in Bihar but only 720 square feet in Assam. Despite the growing adoption of the metric system, katha remains a commonly used unit in land dealings, especially in rural and semi-urban areas.

Katha to other conversion units

Converting katha to other units is essential for accurate land measurement, especially in regions where traditional and modern systems coexist. It ensures clarity in real estate and agricultural transactions.

Acre to katha conversion formula with example

To convert acre to katha, you need to know the local size of a katha in your region. Here’s the general formula for converting acre to katha:

Katha to Acre Conversion:

To convert acres to katha, use the following formula:
Katha = (Acre × 43,560) ÷ Size of 1 Katha in square feet

For example, if 1 katha is equal to 1,360 square feet in a specific region:

  • 1 Acre = 43,560 square feet
  • Number of kathas in 1 acre = 43,560 ÷ 1,360 = 32

So, in this case, 1 acre is equivalent to 32 katha.

Standard conversion rate: 1 acre to katha

In most regions of India, the standard conversion rate betweenacreandkathais1 acre = 32 katha, assuming that1 katha = 1,360 square feet. This conversion is commonly used in states ike Bihar, West Bengal, and parts of Assam.

However, there are regional variations to keep in mind. In some parts of Uttar Pradesh, for example,1 katha can be slightly smaller (about1,400 square feet), which means1 acre may be equal to31 katha instead of 32. It is always important to verify the size of the katha specific to the region where you're dealing with land.

State wise acre to katha measurement units

The conversion from acre to katha differs across India, as the size of 1 katha varies by state. These regional variations make it important to understand local land measurement standards when dealing with property transactions, especially for buyers, sellers, and farmers. To simplify the process of converting between these units, an area converter tool can be incredibly helpful. Here is how it works in different regions:

Bihar: In Bihar,1 katha is typically 1,080 square feet, so 1 acre is roughly equal to 40 katha.

West Bengal: In West Bengal,1 katha is usually considered 1,500 square feet, so 1 acre equals approximately 28-30 katha.

Assam: In Assam, the size of 1 katha is 1,600 square feet, so 1 acre would be approximately 27 katha.

Uttar Pradesh: In parts of UP,1 katha equals around 1,400 square feet, so 1 acre equals about 31 katha.

This regional variation makes it essential to understand the local measurement systems before converting acre to katha.

Area converter tool

To make the process of converting acre to katha simpler, using an area converter tool is highly recommended. These online tools allow you to quickly and accurately convert land measurements by inputting the area in acres and receiving the result in katha. Using a converter tool eliminates any confusion about regional variations and ensures that you get the correct value.

Step-by-step guide to converting acre to katha

Converting acre to katha is simple if you follow these steps:

Understand regional conversions:

The size of 1 katha varies by region in India. Ensure you know the specific conversion rate for the region where the land is located. For example:

West Bengal: 1 acre = 20 kathas

Bihar: 1 acre = 30 kathas

Assam: 1 acre = 16 kathas

Determine the acre measurement:

Identify the number of acres you want to convert to kathas.

Apply the conversion formula:

Multiply the number of acres by the region-specific katha conversion rate.

Example: If you have 2 acres of land in West Bengal, the calculation would be:

2 acres × 20 kathas per acre = 40 kathas.

Use an area converter tool:

For ease and accuracy, use an area converter tool to automatically convert acres to kathas and avoid errors.

Double-check the Conversion:

Verify the conversion based on the local standard to ensure accuracy in land transactions or property dealings.
