Dhur, Katha, Ropani and Bigha in square feet
The numbers people actually type into Google: how many square feet is 10 Dhur, 1 Katha, 1 Ropani or 1 Bigha in Nepal — plus Katha to Ropani, Aana to square metres, and Bigha to hectare.
Most land searches in Nepal are not essays. They are one number and two units: "10 dhur in square feet", "1 katha to ropani", "6 bigha in hectare". The answers are fixed. They do not change by district, and they do not depend on the price of the plot. This page is the chart. The converters do the same arithmetic if you would rather type than read, and how to calculate land area is the longer explanation of how the two systems fit together.
Two systems sit side by side. The hills — including the Kathmandu Valley — use Ropani, Aana, Paisa and Dam. The Terai uses Bigha, Katha and Dhur. Listings then quote the same land in square feet or square metres. Mixing those up is how a 10-Dhur strip gets advertised as if it were 10 Katha.
The short answers
| Unit | Equals | Square feet | Square metres |
|---|---|---|---|
| 1 Dhur | 1/20 Katha | 182.25 | 16.93 |
| 1 Katha | 20 Dhur / 1/20 Bigha | 3,645 | 338.63 |
| 1 Bigha | 20 Katha / 400 Dhur | 72,900 | 6,772.63 |
| 1 Dam | 1/4 Paisa | 21.39 | 1.99 |
| 1 Paisa | 4 Dam / 1/4 Aana | 85.56 | 7.95 |
| 1 Aana | 4 Paisa / 1/16 Ropani | 342.25 | 31.80 |
| 1 Ropani | 16 Aana | 5,476 | 508.74 |
Those square-foot figures are exact. The square-metre column is rounded to two decimals from the international foot (1 m² = 10.7639104167 sq ft). Use the land unit converter if you need more decimal places or a mixed chain such as 1-5-10 Bigha-Katha-Dhur.
Dhur to square feet in Nepal
One Dhur is 182.25 square feet. It is the smallest everyday Terai unit — one twentieth of a Katha. People search it with a count in front because that is how a leftover strip, a road setback or a family split is written on the lalpurja.
| Dhur | Square feet | Square metres | As Katha |
|---|---|---|---|
| 1 Dhur | 182.25 | 16.93 | 0.05 Katha |
| 2 Dhur | 364.50 | 33.86 | 0.10 Katha |
| 3 Dhur | 546.75 | 50.80 | 0.15 Katha |
| 4 Dhur | 729.00 | 67.73 | 0.20 Katha |
| 5 Dhur | 911.25 | 84.66 | 0.25 Katha |
| 6 Dhur | 1,093.50 | 101.59 | 0.30 Katha |
| 7 Dhur | 1,275.75 | 118.52 | 0.35 Katha |
| 8 Dhur | 1,458.00 | 135.46 | 0.40 Katha |
| 9 Dhur | 1,640.25 | 152.39 | 0.45 Katha |
| 10 Dhur | 1,822.50 | 169.32 | 0.50 Katha |
So 10 Dhur in Nepal is 1,822.5 square feet — half a Katha, not half a Ropani. Five Dhur is 911.25 sq ft. Six Dhur is 1,093.5 sq ft. Eight Dhur is 1,458 sq ft. Type any other count into the Dhur to square feet converter, and for the count people ask about most there is a page of its own: 10 Dhur in square feet, with the table out to 20 Dhur and a warning about the Indian Dhur.
1 Katha in square feet in Nepal
One Katha is 3,645 square feet, which is 20 Dhur or one twentieth of a Bigha. That is the figure behind "1 katha sq ft in nepal" and "1 katha to square feet in nepal" — they are the same question.
| Katha | Square feet | Square metres | As Bigha |
|---|---|---|---|
| 1 Katha | 3,645 | 338.63 | 0.05 Bigha |
| 2 Katha | 7,290 | 677.26 | 0.10 Bigha |
| 3 Katha | 10,935 | 1,015.89 | 0.15 Bigha |
| 4 Katha | 14,580 | 1,354.53 | 0.20 Bigha |
| 5 Katha | 18,225 | 1,693.16 | 0.25 Bigha |
| 10 Katha | 36,450 | 3,386.31 | 0.50 Bigha |
| 20 Katha | 72,900 | 6,772.63 | 1 Bigha |
A 5 Katha house plot is 18,225 square feet. Use the Katha to square feet converter for a mixed chain, or the Bigha-Katha-Dhur calculator if the certificate writes 0-5-10.
1 Katha to Ropani — and 1 Ropani to Katha
This is the conversion that does not land on a whole number, because Katha is Terai and Ropani is hill. One Katha is 3,645 ÷ 5,476 = 0.6654 Ropani, which is 10 Aana 2 Paisa 2 Dam plus a small remainder — in conversation, "just over 10.5 Aana". One Ropani is 5,476 ÷ 3,645 = 1.5023 Katha, which is 1 Katha and about 10 Dhur.
| From | To | Exact value |
|---|---|---|
| 1 Katha | Ropani | 0.6654 Ropani (≈ 10 Aana 2 Paisa) |
| 1 Ropani | Katha | 1.5023 Katha (≈ 1 Katha 10 Dhur) |
| 1 Bigha | Ropani | 13.3126 Ropani |
| 1 Ropani | Bigha | 0.0751 Bigha |
Do not treat 1 Ropani as 1.5 Katha in your head and stop there if money is attached. The missing 0.0023 Katha is only about 8 square feet, but the Aana-side rounding is how a listing drifts. The Ropani to Bigha converter and the all-in-one land unit converter keep both chains in step.
1 Bigha in Nepal
One Bigha in Nepal is 72,900 square feet, 20 Katha, 400 Dhur, about 6,772.63 square metres, or 0.6773 hectares. It is also about 13.31 Ropani. "1 bigha to katha" is the easy half of that: multiply by 20. Six Bigha is 437,400 square feet, which is 4.06 hectares — that is the number behind "6 bigha in hectare".
| Bigha | Katha | Square feet | Hectares | Ropani |
|---|---|---|---|---|
| 1 Bigha | 20 | 72,900 | 0.677 | 13.31 |
| 2 Bigha | 40 | 145,800 | 1.355 | 26.63 |
| 5 Bigha | 100 | 364,500 | 3.386 | 66.56 |
| 6 Bigha | 120 | 437,400 | 4.064 | 79.88 |
Go the other way with the Bigha to Katha converter, Bigha to square feet or hectare to Bigha.
1 Aana to square metres
One Aana is 342.25 square feet, which is 31.80 square metres. A 4 Aana valley plot is 1,369 square feet or 127.18 square metres. Aana is the unit house plots are quoted in around Kathmandu, the way Katha is in the Terai.
| Aana | Square feet | Square metres | As Ropani |
|---|---|---|---|
| 1 Aana | 342.25 | 31.80 | 1/16 Ropani |
| 2 Aana | 684.50 | 63.59 | 1/8 Ropani |
| 4 Aana | 1,369.00 | 127.18 | 1/4 Ropani |
| 8 Aana | 2,738.00 | 254.37 | 1/2 Ropani |
| 16 Aana | 5,476.00 | 508.74 | 1 Ropani |
The dedicated page is Aana to square feet. For a survey figure already in square metres, use square metres to Ropani.
Which number is the legal one?
The area printed on the lalpurja is the legal figure. These conversions only change the unit, they do not remeasure the land. If you want to check the shape on the naksa rather than trust a quoted chain, open the sheet in Naapi Plotter — a Mero Kitta map print is the cleanest file to load — and trace the kitta. A few percent off the certificate is normal on a careful trace. A factor of two means the wrong unit, the wrong kitta, or a tilted photo.
These are the standard Nepali definitions used on modern survey paperwork: 1 Ropani = 5,476 sq ft and 1 Bigha = 72,900 sq ft. Older local variants exist in conversation. For registration, transfer or a bank, use the Survey Department record.
