Land Area Converter West Bengal: Bigha · Katha · Decimal · Acre

In West Bengal, 1 Bigha = 20 Katha. Standard in all Banglarbhumi records, land mutation certificates, and WBRERA filings. Since 1 Katha = 720 sq ft, 1 WB Bigha = 14,400 sq ft. Do not use Bihar or UP bigha rates for WB documents — they differ significantly.

1 Katha = 720 square feet in West Bengal — consistent across all districts including Kolkata, Howrah, Burdwan, Hooghly, Nadia, and both 24 Paraganas. The Katha subdivides into 16 Chataks (1 Chatak = 45 sq ft). Most residential plots in WB are sized and priced per Katha.

1 WB Bigha = 33.06 Decimal (rounded to 33 Decimal in practice). Calculation: 1 Acre = 100 Decimal and 1 Acre = 3.025 WB Bigha, so 100 ÷ 3.025 = 33.06 Decimal per Bigha. This conversion is needed in WB mutation paperwork where one document lists Bigha and another lists Decimal.

Decimal = Satak = শতক = 1/100 Acre = 435.6 sq ft. Widely used in WB mutation documents and property registration deeds. "Satak" and "Decimal" are used interchangeably in WB official records. When a deed says "33 decimal", that is approximately 1 Bigha.

No — they differ significantly. West Bengal: 1 Katha = 720 sq ft. Bihar: 1 Katha ≈ 1,361 sq ft (nearly double). Assam and other northeastern states use different local standards. Never use Bihar conversion rates for West Bengal documents — this is a frequent and costly mistake in cross-border land comparisons.

1 Acre = 3.025 Bigha in West Bengal. Conversely, 1 WB Bigha = 0.3306 Acres. Important when comparing agricultural land rates quoted per bigha (common in Hooghly, Burdwan district markets) with rates quoted per acre (common in government acquisition notices and commercial real estate).

1 Chatak = 45 square feet in West Bengal (16 Chatak = 1 Katha = 720 sq ft). Appears in pre-1980 Kolkata and older municipality deeds. Modern property deeds and WBRERA listings do not use Chatak. If found in an old deed, multiply by 45 to convert to square feet.
