1 dismil (decimal) = 435.6 square feet (about 40.47 square metres). A dismil is one-hundredth of an acre, so 100 dismil make 1 acre. To convert dismil to square feet, multiply by 435.6. The unit is the same as the cent used in south India, and it is the everyday land unit in Bihar, Jharkhand, Odisha and West Bengal.
1 Cent / decimal / dismil = 435.6 Square feet (sq ft)
Dismil to square feet formula
Square feet = dismil × 435.6
For example, a 4 dismil plot is 4 × 435.6 = 1,742.4 sq ft. To go the other way, dismil = square feet ÷ 435.6, so a 1,000 sq ft plot is about 2.3 dismil.
