Frequently Asked Questions (FAQ)

Common questions regarding West Bengal land conversions, Banglarbhumi metrics, and ROR records.

In West Bengal land revenue standards, exactly 20 Katha equal 1 Bigha (14,400 Sq. Ft.). 1 Katha equals 720 Sq. Ft.
There is no mathematical difference. "Satak" (শতক) or "Dismil" is colloquial Bengali, while "Decimal" is the statutory English terminology used in official Banglarbhumi deeds. Both represent 435.6 square feet.
Standard West Bengal Land Records (Banglarbhumi) strictly define 1 Katha as exactly 720 Square Feet across all 23 districts.
