Nepalese customary units of measurement

In Nepal, some customary units of measurement are still used, although the metric system has been the official standard since 1968.

Length

The kos is a very ancient measure of distance, measuring about 2.25 miles or 3.7 kilometres.

1 murii = approx. 0.75 inch
4 angul = 1 dharnugrah = 3 in
8 angul = 1 dhanurmushti = 6 in
12 angul = 1 vitastaa = 9 in
2 vitastaa = 18 in
1 haath = 1.5 ft.
1 dand or dhanush = 4 haath = 6 ft
2000 dand = 1 kos or Gorut = 4000 yards or 2.25 miles
4 kosh = 1 yojan = 9 mi = 14.48 km

Land area

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. We may need to convert land area units such as aana to dhur, dhur to aana, kattha to aana, ropani to bigha, square meter to aana, square meter to dhur etc, For such area units conversion you may use .
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 = 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.
;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
1 ana = 4 paisa
1 ropani = 16 ana

Conversions

1 ropani = 74 feet × 74 feet
1 bigha = 13 Ropani 5 Anna
1 kattha = 442 square yards or 338 square meters

Volume

10 Mutthi = 1 Mana
8 Mana = 1 Pathi
20 Pathi = 1 Muri
