690 km2 = 6,900,000,000,000 cm2. To convert square kilometers to square centimeters, multiply by 10,000,000,000: 690 × 10,000,000,000 = 6,900,000,000,000.
How to convert square kilometers to square centimeters
cm2 = km2 × 10,000,000,000
- 1 km2 = 10,000,000,000 cm2 (and 1 cm2 = 1 × 10^-10 km2).
- Multiply the amount by the factor: 690 × 10,000,000,000 = 6,900,000,000,000.
- Answer: 690 km2 = 6,900,000,000,000 cm2.
