Land Measurement in Nepal

The following is a partial list of everyday units used to calculate Land measurement in Nepal.

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[4]
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 the area of land depend 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
Conversions for Terai customary units
Unit Divisions In square metres In square feet
Dhur 16.93 square metres 182.25 square feet
Katha 20 Dhur 338.62 square metres 3,645 square feet
Bigha 20 Katha 6772.41 square metres 72,900 square feet

Hilly and mountainous regions

A different system is used in hilly regions:

1 paisa = 4 dam (daam)
1 ana = 4 paisa
1 ropani = 16 ana

Conversions for Mountainous customary units

Unit Divisions In square metres In square feet
Dam 1.99 square metres 21.39 square feet
Paisa 4 Dam 7.95 square metres 85.56 square feet
Ana 4 Paisa 31.80 square metres 342.25 square feet
Ropani 16 Aana 508.74 square metres 5476 square feet

Conversions

1 ropani = 74 feet × 74 feet
1 bigha = 13 ropani
1 kattha = 442 square yards or 338 square meters
