2.97 mm2 ≈ 2.97 × 10^-12 km2. To convert square millimeters to square kilometers, divide by 1,000,000,000,000: 2.97 ÷ 1,000,000,000,000 = 2.97 × 10^-12.
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: 2.97 × 0 = 2.97 × 10^-12.
- Answer: 2.97 mm2 ≈ 2.97 × 10^-12 km2 (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000,000 gives the same result as multiplying by 0.
