What is Kattha?
कट्ठा
A kattha is a Terai land unit equal to 1/20 of a bigha — 3,645 square feet (about 338.6 m²). It is divided into 20 dhur. Kattha is widely used for house plots and small farms in the plains of Nepal.
1 kattha = 20 dhur = 3,645 sq ft = 338.63 m². Twenty kattha make one bigha.
Kattha is the everyday plot unit in Terai towns, much as aana is in the hills.
