Open Nepali Land Converter1. Understanding Land Measurement Units in Nepal
Nepal uses several traditional land measurement units. The unit used in a property listing or local land transaction may depend on the region.
Hill and urban measurement
Ropani, Aana, Paisa and Daam are commonly used in many hill and urban areas.
Terai measurement
Bigha, Kattha and Dhur are commonly used for land measurement in the Terai.
Metric and modern units
Square feet and square meters are useful for construction, mapping and technical calculations.
Before calculating a plot, identify the measurement system used in your land record, local area or property document. Mixing units without converting them first can lead to incorrect results.
2. Ropani, Aana, Paisa and Daam
The Ropani system is commonly used in many parts of Nepal. One Ropani is divided into 16 Aana, and each Aana is divided into 4 Paisa. Each Paisa is divided into 4 Daam.
1 Ropani = 16 Aana = 64 Paisa = 256 Daam
Ropani system conversion table
| Land unit | Equivalent | Square feet |
|---|---|---|
| 1 Ropani | 16 Aana | 5,476 sq. ft. |
| 1 Aana | 4 Paisa | 342.25 sq. ft. |
| 1 Paisa | 4 Daam | 85.5625 sq. ft. |
| 1 Daam | 1/256 Ropani | 21.390625 sq. ft. |
How to calculate Aana into square feet
To convert Aana into square feet, multiply the number of Aana by 342.25.
Square feet = Aana × 342.25
Example:For 5 Aana:
5 × 342.25 = 1,711.25 square feet
How to calculate Ropani into square feet
Multiply the Ropani value by 5,476.
Square feet = Ropani × 5,476
Example:For 2 Ropani:
2 × 5,476 = 10,952 square feet
3. Bigha, Kattha and Dhur
The Bigha system is widely used in Nepal’s Terai region. A Bigha is divided into 20 Kattha, and each Kattha is divided into 20 Dhur.
1 Bigha = 20 Kattha = 400 Dhur
Terai land measurement conversion table
| Land unit | Equivalent | Square feet |
|---|---|---|
| 1 Bigha | 20 Kattha | 72,900 sq. ft. |
| 1 Kattha | 20 Dhur | 3,645 sq. ft. |
| 1 Dhur | 1/20 Kattha | 182.25 sq. ft. |
How to calculate Kattha into square feet
Multiply the Kattha value by 3,645.
Square feet = Kattha × 3,645
Example:For 3 Kattha:
3 × 3,645 = 10,935 square feet
How to calculate Dhur into square feet
Multiply the Dhur value by 182.25.
Square feet = Dhur × 182.25
Example:For 5 Dhur:
5 × 182.25 = 911.25 square feet

Ropani and square meter
One Ropani is approximately 508.737 square meters. Square meters are useful for modern land records, construction and international measurement comparisons.
| Unit | Square feet | Approx. square meters |
|---|---|---|
| 1 Ropani | 5,476 | 508.737 |
| 1 Aana | 342.25 | 31.796 |
| 1 Bigha | 72,900 | 6,772.63 |
| 1 Kattha | 3,645 | 338.63 |
| 1 Dhur | 182.25 | 16.93 |
Square meter values above are rounded for convenient reading. For official or legal purposes, use the exact conversion standard applicable to your land record.
Quick land measurement reference
| Measurement | Conversion |
|---|---|
| Ropani to Aana | Ropani × 16 |
| Aana to Ropani | Aana ÷ 16 |
| Aana to Paisa | Aana × 4 |
| Paisa to Daam | Paisa × 4 |
| Bigha to Kattha | Bigha × 20 |
| Kattha to Dhur | Kattha × 20 |
| Kattha to square feet | Kattha × 3,645 |
| Ropani to square feet | Ropani × 5,476 |
5. Practical Land Calculation Examples
Example 1: Convert 4 Aana into square feet
Since 1 Aana equals 342.25 square feet:
4 × 342.25 = 1,369 square feet
Example 2: Convert 1 Ropani 8 Aana into square feet
First, convert 1 Ropani:
1 × 5,476 = 5,476 square feet
Then convert 8 Aana:
8 × 342.25 = 2,738 square feet
Add both values:
5,476 + 2,738 = 8,214 square feet
Example 3: Convert 2 Kattha 5 Dhur into square feet
Convert 2 Kattha:
2 × 3,645 = 7,290 square feet
Convert 5 Dhur:
5 × 182.25 = 911.25 square feet
Add both values:
7,290 + 911.25 = 8,201.25 square feet
Example 4: Convert 1 Bigha into Kattha and Dhur
One Bigha contains 20 Kattha. Each Kattha contains 20 Dhur.
1 Bigha = 20 Kattha = 400 Dhur
This relationship makes it easier to calculate large Terai land areas.

Calculate Land Area Online7. Important Tips for Calculating Land Area in Nepal
- Confirm the unit: Make sure your measurement is in Ropani, Aana, Bigha, Kattha, Dhur or another supported unit.
- Do not mix systems: Convert the units to a common unit before adding or comparing areas.
- Check decimal values: Values such as 2.5 Aana or 3.75 Dhur may appear in calculations.
- Use consistent rounding: Keep enough decimal places during calculations and round only the final result.
- Understand area versus dimensions: Land area is not the same as the length of a boundary.
- Verify irregular plots: A plot with an uneven shape may need professional surveying to determine its exact area.
- Check official records: For buying, selling, registration, boundary disputes or construction, verify the area with the relevant land documents and authorities.
Land Area vs. Land Dimensions
Land area tells you how much surface area a plot contains. Land dimensions describe the length and width of its sides.
For a rectangular plot, area can be calculated as:
For example, a rectangular plot measuring 40 feet long and 30 feet wide has an area of:
40 × 30 = 1,200 square feet
This simple formula works for rectangular plots. Irregular plots may require dividing the land into smaller shapes or using a professional survey method.
Conclusion
Calculating land area in Nepal becomes easier when you understand the relationship between Ropani, Aana, Paisa, Daam, Bigha, Kattha and Dhur. The most useful approach is to identify your measurement system, apply the correct conversion formula and verify the result.
For quick conversions, use the WriteNepali online tool instead of doing every calculation manually.
