Introduction

Nepal uses traditional land measurement units that differ from the metric system. Understanding these units is essential for buying, selling, or registering land.

Nepali Land Units

Nepal uses two traditional systems: the hill system (Ropani-based) and the Terai system (Bigha-based), alongside metric units. Understanding these units is essential for buying, selling, or registering land.

Hill system:

  • Ropani — the largest common hill unit (≈508.74 sq meters; some sources cite 508.72 — confirm against the official survey record for legal use)
  • Aana — 1 Ropani = 16 Aana
  • Paisa — 1 Aana = 4 Paisa
  • Daam (also spelled Dam) — 1 Paisa = 4 Daam

Terai system:

  • Bigha — the largest common Terai unit (≈6,772.63 sq meters / about 1.67 acres)
  • Kattha — 1 Bigha = 20 Kattha (≈338.63 sq meters)
  • Dhur — 1 Kattha = 20 Dhur (≈16.93 sq meters)
Approximate values: metric equivalents above are commonly cited conversions (last checked October 2026), not legal survey figures. For transactions, rely on the kitta area in the official Lalpurja and survey records.

Conversion Table

  • **1 Ropani** — 16 Aana ≈ 508.74 m² (some sources 508.72)
  • **1 Aana** — 4 Paisa ≈ 31.80 m²
  • **1 Paisa** — 4 Daam (Dam) ≈ 7.95 m²
  • **1 Bigha** — 20 Kattha ≈ 6,772.63 m²
  • **1 Kattha** — 20 Dhur ≈ 338.63 m²
  • **1 Dhur** ≈ 16.93 m²
