Converting the other way: kilometers to centimeters

centimeters = kilometers × 100,000. So 0.00008 kilometers is back to 8 centimeters; one kilometer is 100,000 centimeters. See the kilometers to centimeters table.

Quick estimate in your head

For a rough answer, multiply by about 0.00001: 8 × 0.00001 ≈ 0.00008 km, against the exact 0.00008 km (0.0% out). Good enough to check that a calculated result is sensible.

Common mistakes

The usual slip is using the factor the wrong way round. A centimeter is smaller than a kilometer, so the number of kilometers must come out smaller than the number of centimeters. If your answer goes the other way, divide instead of multiplying.
