Land measurement varies widely across India, making acre to katha conversion especially important for farmers, buyers, sellers, and anyone dealing with property. While an acre is a standard global unit, katha is a traditional measure used in states like West Bengal, Bihar, Assam, and Odisha. The value of one katha is not uniform across regions, which makes accurate conversion essential during land purchases, sales, and valuation.
Understanding these units is also crucial when applying for a loan against property, since lenders rely on precise land measurements to determine eligibility and loan amounts. Knowing how acre translates to katha ensures transparency and helps you avoid discrepancies during documentation or valuation.
Below, we break down what an acre and a katha represent, how they differ across states, and the conversion methods you need to know for smooth real estate and agricultural transactions.
What is an acre?
An acre is a widely used unit of land measurement, especially for large plots such as agricultural fields, estates, and rural properties. It comes from the imperial system and is still commonly used in India, the United States, and the United Kingdom. One acre equals 43,560 square feet or about 4,047 square metres.
Unlike fixed-shape units, an acre can represent land of any shape, rectangular, circular, or irregular, as long as the total area adds up to 43,560 square feet. This makes it a practical and standard unit for land transactions, valuation, and ownership across both urban and rural regions.
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 widely used in several Indian states, especially Bihar, West Bengal, Assam, and parts of Uttar Pradesh. Unlike standard units such as acres, the size of a katha is not uniform and varies from region to region. In many areas, one katha is treated as approximately 1,360 square feet, but it can range anywhere between 1,200 and 1,800 square feet depending on local usage.
Katha is mostly used to measure smaller land parcels in rural and semi-urban areas, and it remains an important unit in local real estate transactions despite the growing use of metric measurements.
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.

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 between acre and katha is 1 acre = 32 katha, assuming that 1 katha = 1,360 square feet. This conversion is commonly used in states like 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 (about 1,400 square feet), which means 1 acre may be equal to 31 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.
