About the Biswa to Bigha Converter
The biswa is the traditional sub-unit of the bigha in Rajasthan, Uttar Pradesh, Bihar, Himachal Pradesh, Haryana and neighbouring areas. Throughout this region, 1 bigha = 20 biswa (and, in some places, 1 biswa = 20 biswansi). Land is often recorded as, say, "2 bigha 7 biswa".
Because the biswa is a fixed fraction of the bigha, its size in square feet depends on the state's bigha:
| State | 1 bigha (sq ft) | 1 biswa (sq ft) |
|---|---|---|
| Rajasthan – pucca | 27,225 | 1,361.25 |
| Rajasthan – kachha | 17,424 | 871.2 |
| Uttar Pradesh | 27,000 | 1,350 |
| Bihar | 27,220 | 1,361 |
| Himachal Pradesh | 8,712 | 435.6 |
West Bengal and Assam divide the bigha into katha instead of biswa, so this converter is mainly useful for north Indian land.
How to use the Biswa to Bigha Converter
- 1 Choose your state (and pucca or kachha bigha in Rajasthan).
- 2 Enter the number of biswa. For "2 bigha 7 biswa", enter 2 × 20 + 7 = 47 biswa.
- 3 Press Convert.
The formula we use
Bigha = Biswa ÷ 20
Area (sq ft) = Bigha × Size of 1 bigha (sq ft)
Acres = Area ÷ 43,560Worked example
A plot in Rajasthan measures 30 biswa (pucca).
- Bigha = 30 ÷ 20 = 1.5 bigha.
- Area = 1.5 × 27,225 = 40,837.5 sq ft.
- Acres = 40,837.5 ÷ 43,560 = 0.9375 acre.
Things to keep in mind
- Local practice can differ from these standard values. For legal matters, use the area in your official land record.
