Converting the other way: kilometers to micrometers

micrometers = kilometers × 1,000,000,000. So 5e-7 kilometers is back to 500 micrometers; one kilometer is 1,000,000,000 micrometers. See the kilometers to micrometers table.

Quick estimate in your head

For a rough answer, multiply by about 1e-9: 500 × 1e-9 ≈ 5e-7 km, against the exact 5e-7 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 micrometer is smaller than a kilometer, so the number of kilometers must come out smaller than the number of micrometers. If your answer goes the other way, divide instead of multiplying.
