What is Bigha?
बिघा
A bigha is the main land unit of Nepal's Terai (plains). One bigha equals 72,900 square feet (about 6,772.6 m² or 0.677 hectare) and is divided into 20 kattha. 1 bigha ≈ 13.31 ropani.
Bigha is used across the southern Terai districts. 1 bigha = 20 kattha = 400 dhur = 72,900 sq ft = 6,772.63 m².
Hill land uses ropani-aana instead. Agricultural and large plots in the plains are quoted in bigha-kattha-dhur; the converter handles both systems.
