Ropani-Aana-Paisa-Dam calculator
Land in the hills is written as a chain — 2-3-1-2 means 2 Ropani, 3 Aana, 1 Paisa and 2 Dam. Enter the whole chain at once below and read it back in square feet, square inches, square metres or Bigha-Katha-Dhur. It works in reverse as well: type an area and the chain is filled in for you.
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.

About this unit
Ropani is the standard land unit across the Kathmandu Valley and the hill districts. A Ropani divides into 16 Aana, each Aana into 4 Paisa, and each Paisa into 4 Dam, so one Dam is 21.390625 square feet.
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.

From your naksa
Upload a photo or scan of a naksa, kitta map or site plan, calibrate it once against a length you know, and tap around the plot boundary. Works with iPhone HEIC photos.
From tape measurements
Measured the plot yourself? Sketch the shape, press auto-triangulate, and enter each length in feet, inches, metres or centimetres.

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.
