Dhur and Katha are traditional land measurement units widely used in several parts of India and Nepal for identifying and calculating land area, especially in rural and semi-urban regions. These units remain highly relevant in property transactions, agricultural land division, inheritance cases, and local revenue records. Although modern systems use acres, hectares, and square feet, many official land documents in states like Bihar, Jharkhand, Uttar Pradesh, and West Bengal still mention dhur to katha measurements. Understanding these units is essential for accurate land valuation and legal clarity.
The dhur measurement represents a very small portion of land, while the katha measurement is a larger unit made up of multiple dhurs. Their relationship forms the basis of many traditional land calculations used in land records. Since land values vary significantly across regions, incorrect interpretation of these units can lead to disputes or financial losses. Therefore, knowing how land measurement units like dhur and katha work is crucial for buyers, sellers, farmers, and real estate professionals.
What is Dhur in land measurement?
Dhur is a traditional land measurement unit used mainly in eastern India and Nepal. It represents a very small portion of land area and is considered the smallest subunit in the dhur to katha system. Typically, multiple dhurs make up one katha, commonly 20 dhur = 1 katha in many regions. Dhur is widely used in Bihar, Jharkhand, West Bengal, Assam, and Nepal (Terai region) for measuring agricultural and residential plots. It plays an important role in rural land records, property division, and revenue documentation. Since dhur values can vary slightly across districts, local land records are always used for accurate verification during buying, selling, or registering property.
What is Katha in land measurement?
Katha is a traditional unit of land measurement commonly used in parts of India such as Bihar, Jharkhand, Uttar Pradesh, and West Bengal, as well as in Nepal. It is primarily used for measuring residential and agricultural land in rural and semi-urban areas. In most regions, 1 Katha is equal to 20 Dhur, although the exact size in square feet can vary depending on local revenue standards and state-specific rules. Katha plays an important role in land records, property transactions, inheritance division, and agricultural planning. Despite the use of modern metric units, Katha remains widely used in official documents and local land dealings due to its deep historical and regional significance.
Dhur and Katha overview
| Unit | meaning | Common usage regions |
|---|---|---|
| Dhur | Smallest traditional subunit derived from local rod-based measurements | Bihar, Jharkhand, West Bengal, Tripura, Assam, Nepal (Terai) |
| Katha | Standard land unit equal to 20 Dhurs | North & East India, parts of Madhya Pradesh, Nepal |
These units are essential for property division, land valuation, and agricultural planning.
Dhur to katha conversion formula
The conversion between dhur and katha is based on a fixed relationship used in most regions:
Formula:
Katha = Dhur ÷ 20
This means 20 dhurs make 1 katha.
Example calculations:
- 10 Dhur = 10 ÷ 20 = 0.5 Katha
- 25 Dhur = 25 ÷ 20 = 1.25 Katha
- 50 Dhur = 50 ÷ 20 = 2.5 Katha
- 100 Dhur = 100 ÷ 20 = 5 Katha
Accurate conversion is important for land valuation, registration, and property transactions to avoid legal discrepancies.

Regional variations of Dhur and Katha across India
The values of dhur and katha vary significantly across India due to historical and regional land measurement practices. While the basic relationship remains similar, the actual square-foot value differs.

West Bengal has much smaller dhur and katha units
How to convert Dhur to Katha manually?
Understand the basic formula:
1 Katha = 20 Dhur, so Katha = Dhur ÷ 20
Step 1: Note the total Dhur value
Check land records such as Khatauni, sale deed, or revenue documents to find the exact land measurement in Dhur.
Step 2: Apply the conversion formula
Divide the total Dhur by 20 to get the value in Katha.
Step 3: Calculate carefully
Example:
- 10 Dhur ÷ 20 = 0.5 Katha
- 50 Dhur ÷ 20 = 2.5 Katha
- 100 Dhur ÷ 20 = 5 Katha
Step 4: Verify with land records
Cross-check the result with official revenue documents or local authorities to ensure accuracy.
Step 5: Avoid calculation errors
Use a calculator or conversion chart to prevent mistakes in property valuation or legal documentation.
