Easily convert land measurements between the Hilly system (Ropani-Aana), Terai system (Bigha-Kattha), and standard units (Sq. Feet/Meters). Type in any field, and the rest will update automatically.
(Ropani - Aana - Paisa - Dam)
The common base unit for calculation.
(Bigha - Kattha - Dhur)
In Nepal, the standard accepted measurement for **1 Ropani is 5,476 Square Feet**. This is the most common unit used in hilly regions like Kathmandu valley.
There are approximately **342.25 Square Feet in 1 Aana**. Since 16 Aana makes 1 Ropani, you can calculate this by dividing 5476 by 16.
A Bigha is a larger unit used primarily in the Terai plains. **1 Bigha is equivalent to 72,900 Square Feet** or approximately 6,772.63 Square Meters.
This tool uses standard mathematical formulas based on Nepal's official land measurement units. When you enter a value in any field (like Dhur or Aana), the calculator instantly converts that base value into Square Feet, and then calculates equivalent values for all other units simultaneously.
