The short version:

Nepal uses two land systems: in the hills and Kathmandu Valley, 1 Ropani = 16 Aana = 64 Paisa = 256 Daam = 5,476 sq ft; in the Terai, 1 Bigha = 20 Kattha = 400 Dhur = 72,900 sq ft. Convert everything through square feet: 1 Aana is 342.25 sq ft and 1 Kattha is 3,645 sq ft.

Which land units are used in Nepal?

Land certificates (lalpurja) and property listings use one of two traditional systems:

  • Hill system — Ropani, Aana, Paisa, Daam. Used in the hills and in the Kathmandu Valley. Prices for urban plots are usually quoted per Aana.
  • Terai system — Bigha, Kattha, Dhur. Used in the plains of the Terai. Prices are usually quoted per Kattha or per Dhur.

Builders, banks and architects also use square feet and square metres, so you often need to move between all of them.

How do the units relate to each other?

A Ropani is a square of 74 ft × 74 ft, and an Aana is 18.5 ft × 18.5 ft. Square metres here use the exact foot (0.3048 m); you will sometimes see 508.72 m² for a Ropani because of rounding in older tables.

Between the two systems:

  • 1 Bigha ≈ 13.31 Ropani
  • 1 Kattha ≈ 10.65 Aana
  • 1 Ropani ≈ 1.50 Kattha

How do I read a figure like 2-8-2-0?

Hill-system areas are written largest unit first: Ropani–Aana–Paisa–Daam. So 2-8-2-0 means 2 Ropani, 8 Aana, 2 Paisa and 0 Daam. Terai areas are written Bigha–Kattha–Dhur, so 1-5-10 means 1 Bigha, 5 Kattha and 10 Dhur.

Worked examples

1. 2-8-2-0 (Ropani–Aana–Paisa–Daam) in square feet

2 Ropani 8 Aana 2 Paisa
2 ROPANI × 5,47610,952 sq ft
8 AANA × 342.252,738 sq ft
2 PAISA × 85.5625171.13 sq ft
TOTAL13,861.13 sq ft ≈ 1,287.74 m²

That is about 3.80 Kattha in the Terai system.

2. 5 Kattha 10 Dhur in square feet and Aana

  • 5 × 3,645 = 18,225 sq ft
  • 10 × 182.25 = 1,822.5 sq ft
  • Total 20,047.5 sq ft (about 1,862.47 m²), which is about 58.58 Aana, or 3 Ropani 10 Aana and a little more.

3. A 4 Aana house plot priced at Rs 35,00,000 per Aana

4 Aana = 1,369 sq ft. The land price is 4 × Rs 35,00,000 = Rs 1,40,00,000, which works out to about Rs 10,226 per sq ft.

Why do figures differ between sources?

The square-foot values in the table are the standard ones and do not change. Differences you see online come from rounding square metres (508.72 vs 508.74 for a Ropani) or from converting through rounded intermediate figures — always convert through square feet. For a sale, registration or bank loan, rely on the area written on the land ownership certificate and the cadastral map from the Survey Office.

Frequently asked questions

How many square feet are in 1 Aana?

One Aana is 342.25 square feet, or about 31.80 square metres. Sixteen Aana make one Ropani of 5,476 square feet.

How many Kattha are in 1 Bigha?

One Bigha has 20 Kattha, and one Kattha has 20 Dhur, so a Bigha is 400 Dhur. In square feet, a Bigha is 72,900 and a Kattha is 3,645.

How many Ropani make 1 Bigha?

About 13.31 Ropani. A Bigha is 72,900 square feet and a Ropani is 5,476 square feet, so 72,900 ÷ 5,476 ≈ 13.31.

How do I convert Aana to Dhur?

Go through square feet: multiply the Aana by 342.25 and divide by 182.25. One Aana is about 1.88 Dhur. The land area converter does this for any mix of units.
