0.75 mm ≈ 7.5 × 10^-7 km. To convert millimeters to kilometers, divide by 1,000,000: 0.75 ÷ 1,000,000 = 7.5 × 10^-7.
How to convert millimeters to kilometers
km = mm × 0.000001
- 1 mm = 0.000001 km (and 1 km = 1,000,000 mm).
- Multiply the amount by the factor: 0.75 × 0.000001 = 7.5 × 10^-7.
- Answer: 0.75 mm ≈ 7.5 × 10^-7 km (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000 gives the same result as multiplying by 0.000001.
