West Bengal Katha to square feet
One Cottah is documented as 720 sq ft in a Kolkata metropolitan context. Convert it transparently and verify the parcel record.
The published Kolkata-area context
An official Comptroller and Auditor General report states that one Cottah equals 720 square feet in the described Kolkata Metropolitan Development Authority land context. GharGanit labels 720 sq ft as customary rather than presenting it as one universal legal value for every West Bengal district.
