About Land Area (Ropani/Bigha)
Nepal uses two traditional land systems: the hill system (ropani–aana–paisa–dam, used in Kathmandu, Pokhara and the hills) and the Tarai/plain system (bigha–kattha–dhur). Property listings, lalpurja (य सदपति) and malpot paperwork mix them freely with square feet and square metres, so mistakes are common.
Standard conversions: 1 ropani = 16 aana = 5,476 sq ft ≈ 508.74 m²; 1 aana = 342.25 sq ft; 1 bigha = 20 kattha = 72,900 sq ft ≈ 6,772.6 m²; 1 kattha = 3,645 sq ft; 1 dhur = 182.25 sq ft.

QWhy do Kathmandu listings use ropani but Tarai listings use bigha?
The hill system comes from historic hill-district usage, and the bigha–kattha–dhur system came with the Tarai's agrarian history. The lalpurja will state whichever system your district uses.
