Free Nepali land area converter: type a value in any unit — ropani, aana, paisa, daam, bigha, kattha, dhur, square feet, square meters or hectares — and every other field converts instantly. The result panel also shows the area broken down the way land documents (लालपुर्जा) write it: रोपनी–आना–पैसा–दाम for hill districts and बिघा–कठ्ठा–धुर for the Terai.
Nepal uses two traditional land measurement systems. The hill system (Kathmandu valley and hilly districts) measures in ropani, where 1 ropani = 16 aana, 1 aana = 4 paisa, 1 paisa = 4 daam. The Terai system (Madhesh) measures in bigha, where 1 bigha = 20 kattha and 1 kattha = 20 dhur. Government records increasingly use square meters, while builders and real-estate listings quote square feet — this tool converts between all of them exactly.

Frequently Asked Questions (FAQ)
How many aana are there in one ropani?
16 aana = 1 ropani. One aana is further divided into 4 paisa, and one paisa into 4 daam — so a ropani has 64 paisa or 256 daam.
How many square feet is one aana?
One aana is 342.25 sq ft (about 31.80 m²). A typical 4-aana plot in Kathmandu is 1,369 sq ft.
How many kattha in one bigha, and dhur in one kattha?
1 bigha = 20 kattha, and 1 kattha = 20 dhur. One kattha is 3,645 sq ft — slightly larger than 10 aana.
Is one bigha bigger than one ropani?
Much bigger: 1 bigha = 72,900 sq ft ≈ 13.31 ropani. Bigha is used in the flat Terai where holdings are larger; ropani in the hills.
Why does my lalpurja show square meters?
Newer survey maps and land certificates record area in square meters (and hectares for large plots). Enter the m² figure from your लालपुर्जा above to see it in ropani/aana or bigha/kattha instantly.
