Understanding Nepal Land Measurement Units: Terai vs Hilly Systems Explained
A clear guide to converting Bigha, Katha, Dhur (used in Dhangadhi, Kailali, and the Terai) into Ropani, Aana, Paisa, Daam (used in Kathmandu and Hilly regions) and Square Feet / Square Meters.
In Nepal, land measurement follows two distinct historical systems based on geography: the Terai System (Bigha-Katha-Dhur) and the Hilly System (Ropani-Aana-Paisa-Daam). Understanding both is crucial for property transactions and investment analysis.
1. The Terai System (Standard in Dhangadhi, Kailali, and southern plains):
• 1 Bigha = 20 Katha = 400 Dhur = 72,900 sq.ft. (approx. 6,772.63 sq. meters)
• 1 Katha = 20 Dhur = 3,645 sq.ft. (approx. 338.63 sq. meters)
• 1 Dhur = 182.25 sq.ft. (approx. 16.93 sq. meters)
2. The Hilly System (Standard in Kathmandu Valley and hilly districts):
• 1 Ropani = 16 Aana = 5,476 sq.ft. (approx. 508.74 sq. meters)
• 1 Aana = 4 Paisa = 342.25 sq.ft. (approx. 31.80 sq. meters)
• 1 Paisa = 4 Daam = 85.56 sq.ft. (approx. 7.95 sq. meters)
• 1 Daam = 21.39 sq.ft. (approx. 1.99 sq. meters)
3. Practical Quick Conversion Rules:
1 Bigha is equal to approximately 13.31 Ropani. 1 Katha is equal to approximately 10.65 Aana. 1 Ropani is equal to approximately 1.50 Katha.
