In Nepal, two types of unit systems are used for land area measurements. In hilly regions, ropani-aana-paisa-daam units are used, while in terai regions, bigha-kattha-dhur units measurements are used. The precise
land measurement conversions as per Nepal standard are as follows: In a nutshell, The following is a partial list of everyday units used to calculate land area in Nepal. • 1 Khetmuri = 25 Ropani • 1 Bigha (बिघा) = 20 Kattha (कठ्ठा) = 6772.63 m2 = 72900 sq.ft. = 13.31 Ropani • 1 Katha (कठ्ठा) = 20 Dhur (धुर) = 338.63 m2 = 3645 sq.ft. • 1 Dhur (धुर) = 16.93 m2 = 182.25 sq.ft. • 1 Ropani (रोपनी) = 16 Aana (आना) = 64 Paisa (पैसा) = 508.72 m2 = 5476 sq.ft. = 256 Daam (दाम) = 4 llka • 1 Aana (आना)= 4 Paisa (पैसा) = 31.80 m2 = 342.25 sq. ft. = 16 Daam (दाम) • 1 Paisa (पैसा) = 4 Daam (दाम) = 7.95 m2 = 85.56 sq. ft. • 1 Daam (दाम) = 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. ;
Terai region In the Terai region, the southern parts of Nepal, the customary units are those used elsewhere in South Asia: • 1
katha = 20 dhur • 1
bigha = 20 katha ;Hilly and mountainous regions A different system is used in hilly regions: • 1 paisa = 4 dam (daam) • 1 ana (aana) = 4 paisa ==Volume==
