How it is calculated
Convert to square feet first, then divide by the size of one Katha: 1 Acre × 43,560 sq ft = 43,560 sq ft, and 43,560 ÷ 720 = 60.5 Katha.
For a mixed area, add the parts in sq ft first. Example: 1 Katha 8 Chatak = 720 + 8 × 45 = 1,080 sq ft = 2.48 Decimal.

Why other websites show different numbers
West Bengal uses 1 Bigha = 20 Katha = 14,400 sq ft, with 1 Katha = 720 sq ft and 1 Chatak = 45 sq ft. The same names mean different sizes in other places, and many national websites mix them up:
- Some sites give a Katha of 1,361.25 sq ft. That is a Bihar value, not a West Bengal one.
- Assam also uses a Bigha of 14,400 sq ft, but splits it into 5 Katha, so an Assam Katha is 2,880 sq ft.
- Some sites give about 1.6 Bigha per Acre. That is a much larger Bigha used in parts of north India. In West Bengal, 1 Acre = 3.025 Bigha.
- Some pages contradict themselves, for example "20 Katha = 1 Bigha" and "1 Bigha = 37.38 Katha" on the same page.
- Sites and videos from Bangladesh use the same names (Bigha, Katha, Shotok), but local sizes there can differ by area, so check which region a source is about.
These are the West Bengal real-estate standard conversions. Bigha size historically varied by district and estate, and Ganda is rarely used today.
