Convert between Nepal's two traditional land measurement systems — Ropani-Aana-Paisa-Daam (hill regions) and Bigha-Kattha-Dhur (Terai) — and square feet or square metres. Enter a value in any one field and every other field updates.
Nepal uses two traditional land measurement systems depending on the region. In the hills and Kathmandu Valley: 1 Ropani = 16 Aana = 64 Paisa = 256 Daam = 5,476 sq. ft. In the Terai (southern plains): 1 Bigha = 20 Kattha = 400 Dhur = 72,900 sq. ft. The two systems are not used interchangeably by area alone — which one applies depends on where the land is, not the size.
