Ropani-Aana-Paisa-Dam and Bigha-Katha-Dhur calculator

Land is rarely a single number on paper — it is written as a chain, like 2-3-1-2 Ropani-Aana-Paisa-Dam or 1-5-10 Bigha-Katha-Dhur. Enter the whole chain here and read it back in square feet, square inches or square metres, or type an area and let the chains fill themselves in. Every row stays in step with the others.

Area Plotter uses the standard Nepali land units: 1 Ropani = 16 Aana = 64 Paisa = 256 Dam = 5,476 square feet, and 1 Bigha = 20 Katha = 400 Dhur = 72,900 square feet.

Can I enter Ropani, Aana, Paisa and Dam together?

Yes. The calculator on this page takes the whole chain at once — Ropani-Aana-Paisa-Dam or Bigha-Katha-Dhur — and converts it to square feet, square inches and square metres. It works in reverse too: enter an area and the chains are filled in for you.

Can I measure my own land instead of converting a number?

Yes. GharNaksa Naapi Plotter can measure a plot directly from a photo or scan of your naksa. Calibrate it once against a length you know, tap around the boundary, and the area comes out in every unit at once. The same tool has a dimension tool for reading the distance between any two points on the drawing.
