Quick estimate in your head
For a rough answer, multiply by about 0.0003: 15 × 0.0003 ≈ 0.0045 km, against the exact 0.004572 km (1.6% 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 foot is smaller than a kilometer, so the number of kilometers must come out smaller than the number of feet. If your answer goes the other way, divide instead of multiplying.
