Converting the other way: meters to kilometers

kilometers = meters × 0.001. So 1,000 meters is back to 1 kilometer; one meter is 0.001 kilometers. See the meters to kilometers table.

Quick estimate in your head

For a rough answer, multiply by about 1000: 1 × 1000 ≈ 1,000 m, against the exact 1,000 m (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 kilometer is bigger than a meter, so the number of meters must come out larger than the number of kilometers. If your answer goes the other way, divide instead of multiplying.
