Area Converter Information

The following is a list of everyday units used to calculate land area in Nepal.

  • 1 Bigha = 20 Kattha = 6772.63 m² = 72900 sq.ft. = 13.31 Ropani
  • 1 Katha= 20 Dhur = 338.63 m² = 3645 sq.ft.
  • 1 Dhur = 16.93 m² = 182.25 sq.ft.
  • 1 Ropani = 16 Aana = 64 Paisa = 508.72 m² = 5476 sq.ft. = 256 Daam = 4 llka
  • 1 Aana = 4 Paisa = 31.80 m² = 342.25 sq. ft. = 16 Daam
  • 1 Paisa = 4 Daam = 7.95 m² = 85.56 sq. ft.
  • 1 Daam = 1.99 m² = 21.39 sq. ft.

The units of measurement of area of land depends on the part of the country where they are being used, with the Bigha-Katha-Dhur measurements common in the Terai region while the Ropani-Aana measurements are common in hilly and mountainous regions.
