746 cm2 ≈ 7.46 × 10^-8 km2. To convert square centimeters to square kilometers, divide by 10,000,000,000: 746 ÷ 10,000,000,000 = 7.46 × 10^-8.
How to convert square centimeters to square kilometers
km2 = cm2 × 1 × 10^-10
- 1 cm2 = 1 × 10^-10 km2 (and 1 km2 = 10,000,000,000 cm2).
- Multiply the amount by the factor: 746 × 1 × 10^-10 = 7.46 × 10^-8.
- Answer: 746 cm2 ≈ 7.46 × 10^-8 km2 (rounded to 6 significant figures).
Shortcut: dividing by 10,000,000,000 gives the same result as multiplying by 1 × 10^-10.
