Square centimeter to square decimeter Conversion
1 square centimeter (cm²) is equal to 0.01 square decimeter (dm²).
1 cm² = 0.01 dm²
or
1 dm² = 100 cm²
Formula
To convert a area from square centimeter (cm²) to square decimeter (dm²), divide the area in square centimeter by 100
a(dm²) = a(cm²) / 100
Examples:
Convert 10 square centimeter to square decimeter:
a(dm²) = 10cm² / 100 = 0.1 dm²
