Square millimeter to Square centimeter
Square millimeter (mm²)
Square centimeter (cm²)
How it is calculated
Each unit is defined via the base unit (square meter (m²)). The value is first converted to the base unit, then to the selected unit.
1 mm² = 1.00000000e-6 m²
1 cm² = 0.0001 m²
1 mm² × 1.00000000e-6 = 1.00000000e-6 m²
1.00000000e-6 m² ÷ 0.0001 = 0.01 cm²
