Nepali Area Converter
Ropani, Aana, Paisa, Daam for the hills — Bigha, Kattha, Dhur for the Terai — plus sq ft and sq m.
Convert land area between Nepal's two traditional systems — Ropani/Aana/Paisa/Daam used in hill and mountain districts, and Bigha/Kattha/Dhur used in the Terai — and between either system and square feet or square metres.
Hill system (Ropani, Aana, Paisa, Daam)
| Unit | Equal to |
|---|---|
| 1 Ropani | 16 Aana · 5,476 sq ft · 508.72 m² |
| 1 Aana | 4 Paisa · 342.25 sq ft |
| 1 Paisa | 4 Daam · 85.56 sq ft |
| 1 Daam | 21.39 sq ft |
Terai system (Bigha, Kattha, Dhur)
| Unit | Equal to |
|---|---|
| 1 Bigha | 20 Kattha · 72,900 sq ft · 6,772.6 m² |
| 1 Kattha | 20 Dhur · 3,645 sq ft |
| 1 Dhur | 182.25 sq ft |
Common land sizes
| Size | Square feet | Square meters |
|---|---|---|
| 1 Aana | 342.25 sq ft | 31.8 m² |
| 4 Aana (a typical house plot in Kathmandu) | 1,369 sq ft | 127.2 m² |
| 1 Ropani | 5,476 sq ft | 508.7 m² (about 0.126 acres) |
| 1 Kattha | 3,645 sq ft | 338.6 m² |
| 1 Bigha | 72,900 sq ft | 6,772.6 m² (about 1.67 acres) |
Comparing the two systems
One Bigha is about 13.3 Ropani, and one Kattha is about 10.65 Aana. To compare land in the hills with land in the Terai, convert both to square feet or square meters first.
Worked example
A plot of 5 Aana 2 Paisa:
- 5 Aana × 342.25 = 1,711.25 sq ft
- 2 Paisa × 85.56 = 171.12 sq ft
- Total ≈ 1,882.4 sq ft, or about 174.9 m²
Before buying land
- Check the lalpurja (land ownership certificate) for the official area and its unit.
- Get the plot measured by an authorized surveyor — the actual area can differ slightly from the documents.
- Watch for road setbacks, which can reduce the area you're allowed to build on.
For square feet, acres and hectares, use the area converter.
Frequently asked questions
How many square feet is 1 Ropani?
1 Ropani = 5,476 square feet ≈ 508.7 square metres, and splits into 16 Aana, 64 Paisa, or 256 Daam.
How many square feet is 1 Bigha?
1 Bigha = 72,900 square feet ≈ 6,772.6 square metres, and splits into 20 Kattha or 400 Dhur.
Which system should I use — Ropani or Bigha?
Ropani/Aana/Paisa/Daam is used in the hill and mountain districts (including Kathmandu Valley); Bigha/Kattha/Dhur is used in the Terai (plains) region. Use whichever matches how the land is measured locally.
How many Aana are in a Ropani?
1 Ropani = 16 Aana. Each Aana is 4 Paisa, and each Paisa is 4 Daam, so 1 Ropani = 64 Paisa = 256 Daam.
