421 mm³ = 0.421 cm³. To convert cubic millimeters to cubic centimeters, divide by 1,000: 421 ÷ 1,000 = 0.421.
How to convert cubic millimeters to cubic centimeters
cm³ = mm³ × 0.001
- 1 mm³ = 0.001 cm³ (and 1 cm³ = 1,000 mm³).
- Multiply the amount by the factor: 421 × 0.001 = 0.421.
- Answer: 421 mm³ = 0.421 cm³.
Shortcut: dividing by 1,000 gives the same result as multiplying by 0.001.
