Hill notation: ropani-aana-paisa-dam
Land in the hills is written R-A-P-D. Read the four numbers from left to right: ropani, aana, paisa, dam. The dashes only separate the numbers; they are not minus signs.
The units step down by fixed ratios:
- 1 ropani = 16 aana = 64 paisa = 256 dam
- 1 aana = 4 paisa
- 1 paisa = 4 dam
In square feet, 1 ropani = 5,476 sq ft, 1 aana = 342.25 sq ft, 1 paisa = 85.5625 sq ft and 1 dam = 21.390625 sq ft.
Terai notation: bigha-kattha-dhur
In the Terai, area is written B-K-D: bigha-kattha-dhur. 1 bigha = 20 kattha and 1 kattha = 20 dhur, so 1-2-3 means 1 bigha, 2 kattha and 3 dhur.
In square feet, 1 bigha = 72,900 sq ft, 1 kattha = 3,645 sq ft and 1 dhur = 182.25 sq ft.
