Nepal Land Area Systems & Conversion Standards
Nepal officially uses two traditional land measurement systems alongside metric units (square meters): the Ropani System (hilly regions & Kathmandu Valley) and the Bigha System (Terai region including Sunsari, Morang, and Jhapa).
Terai / Bigha System (Sunsari & Morang)
- 1 Bigha = 20 Kattha = 72,900 sq.ft. (6,772.63 m²)
- 1 Kattha = 20 Dhur = 3,645 sq.ft. (338.63 m²)
- 1 Dhur = 182.25 sq.ft. (16.93 m²)
- 1 Kanwa = 1/16 Dhur = 11.39 sq.ft.
Hills / Ropani System
- 1 Ropani = 16 Aana = 5,476 sq.ft. (508.74 m²)
- 1 Aana = 4 Paisa = 342.25 sq.ft. (31.80 m²)
- 1 Paisa = 4 Daam = 85.56 sq.ft. (7.95 m²)
- 1 Daam = 21.39 sq.ft. (1.99 m²)
Note on Municipal Bylaws: For residential building permit approval in Itahari and Dharan, municipalities enforce minimum frontage and area requirements (typically minimum 10 Dhur or 2.5 Aana with access road right-of-way).
