Decimal / Dismil to Square Feet — East India

Decimal (also spelled dismil or decimel) equals 435.6 sq ft in BhumiMeter's nationwide fixed table — widely used in West Bengal, Bihar, Jharkhand, and Assam alongside Katha and Bigha. 100 decimals = 1 acre (43,560 sq ft). Essential for RoR and mutation copies that still list "12.5 decimal".

Decimal vs Katha vs Bigha

In Patna brokers, 1 Katha (Patna) = 1,361.25 sq ft while 1 decimal = 435.6 sq ft — different chains. Bengal listings may say "3 katha 5 decimal" meaning Katha plus decimal fractions, not 3.5 of one unit. Always parse the exact words on the deed.

Mutation and stamp duty

Circle offices often aggregate decimal fractions across co-sharers. Before registry, convert total decimal to sq ft and match the survey sketch. Discrepancies of even 1–2 decimal (435.6 sq ft each) trigger re-measurement delays.
