0.045 m2 ≈ 4.5 × 10^-8 km2. To convert square meters to square kilometers, divide by 1,000,000: 0.045 ÷ 1,000,000 = 4.5 × 10^-8.
How to convert square meters to square kilometers
km2 = m2 × 0.000001
- 1 m2 = 0.000001 km2 (and 1 km2 = 1,000,000 m2).
- Multiply the amount by the factor: 0.045 × 0.000001 = 4.5 × 10^-8.
- Answer: 0.045 m2 ≈ 4.5 × 10^-8 km2 (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000 gives the same result as multiplying by 0.000001.
