Add Another Conversion Table
A versatile unit converter to accurately translate between Standard units, the Mountain system (Ropani-Aana), and the Terai system (Bigha-Kattha).
Using the ShaSWi Area Converter is simple and instant. There are no complicated dropdowns—just directly enter your land value into any of the unit fields (like 1 Ropani, 4 Aana, or 10 Bigha). The tool will immediately output the exact conversions across all other major Nepali systems and standard units like Square Feet (Sq.Ft) and Meters (Sq.M). You can edit the data in any unit cell at any time.

Predominantly used in the hilly regions of Nepal, including the Kathmandu Valley. The standard breakdown is Ropani - Aana - Paisa - Daam.
Widely used in the flat, southern plains (Terai) of Nepal. The calculation system is Bigha - Kattha - Dhur.
1 Ropani is exactly equal to 5,476 square feet (sq ft).
1 Aana is equal to 342.25 square feet. So, a popular plot size like 4 Aana would be 1,369 square feet.
Bigha is a much larger land unit used in the Terai region, while Ropani is used in the Hilly regions. 1 Bigha equals 72,900 sq ft, whereas 1 Ropani is only 5,476 sq ft. Therefore, 1 Bigha is a little over 13 Ropani!
To convert a Bigha value, simply multiply it by 72,900. Or, skip the math entirely by typing your value directly into the "Bigha" field in our calculator above to automatically get the square footage.
