Which unit do CMDA documents use?
CMDA documents primarily use square metres (sq m) — SI standard. Revenue records (patta) use cents. Sale deeds often dual — sq ft + sq m. Architect drawings: sq ft on plans for client readability + sq m for area calculations matching CMDA.
How do I convert sq ft to sq m quickly?
Divide by 10.76. So 1,500 sq ft = 1,500/10.76 = 139.4 sq m. Or use the reverse: sq m × 10.76 = sq ft. For mental math: sq m ≈ sq ft / 11.
