421 m³ ≈ 4.21 × 10^-7 km³. To convert cubic meters to cubic kilometers, divide by 1,000,000,000: 421 ÷ 1,000,000,000 = 4.21 × 10^-7.
How to convert cubic meters to cubic kilometers
km³ = m³ × 1 × 10^-9
- 1 m³ = 1 × 10^-9 km³ (and 1 km³ = 1,000,000,000 m³).
- Multiply the amount by the factor: 421 × 1 × 10^-9 = 4.21 × 10^-7.
- Answer: 421 m³ ≈ 4.21 × 10^-7 km³ (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000 gives the same result as multiplying by 1 × 10^-9.
