710 mm2 ≈ 7.1 × 10^-10 km2. To convert square millimeters to square kilometers, divide by 1,000,000,000,000: 710 ÷ 1,000,000,000,000 = 7.1 × 10^-10.
How to convert square millimeters to square kilometers
km2 = mm2 × 0
- 1 mm2 = 0 km2 (and 1 km2 = 1,000,000,000,000 mm2).
- Multiply the amount by the factor: 710 × 0 = 7.1 × 10^-10.
- Answer: 710 mm2 ≈ 7.1 × 10^-10 km2 (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000,000 gives the same result as multiplying by 0.
