Reading an area like 2-5-1-3

A lalpurja (land ownership certificate) writes a hill area as four numbers: 2-5-1-3 means 2 ropani, 5 aana, 1 paisa and 3 dam. A Terai area is three: 1-4-10 is 1 bigha, 4 kattha and 10 dhur. Choose the matching tab above and type each part.

Square metres here use the exact international foot (1 sq ft = 0.09290304 m²). Some printed tables round the factor and show 508.72 m² for a ropani; the difference is under a hundredth of a percent.
