720 km2 = 720,000,000,000,000 mm2. To convert square kilometers to square millimeters, multiply by 1,000,000,000,000: 720 × 1,000,000,000,000 = 720,000,000,000,000.
How to convert square kilometers to square millimeters
mm2 = km2 × 1,000,000,000,000
- 1 km2 = 1,000,000,000,000 mm2.
- Multiply the amount by the factor: 720 × 1,000,000,000,000 = 720,000,000,000,000.
- Answer: 720 km2 = 720,000,000,000,000 mm2.
