Quick estimate in your head

For a rough answer, multiply by about 0.002: 5 × 0.002 ≈ 0.01 km, against the exact 0.009144 km (9.4% 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 fathom is smaller than a kilometer, so the number of kilometers must come out smaller than the number of fathoms. If your answer goes the other way, divide instead of multiplying.
