In Nepal we use different units for measurement of land. In hilly regions we use Ropani-Ana-Paisa-Dam system while in Southern parts i.e. at Terai region we use Bhigha-Kattha-Dhur system.
The conversion between these units and also to the SI unit is essential as we come across this situation often.
The conversion factor for these units is as follows
1 Ropani =16Ana
1 Ana =4 Paisa
1Paisa =4 Dam
1 Bhigha= 20 Kattha
1 Kattha= 20 Dhur
For inter conversion between Ropani and Bhigha
Similarly in standard units we may use
1 Ropani =74feet X 74 feet
1 m=3.281 feet
