Quick estimate in your head

For a rough answer, multiply by about 500: 13 × 500 ≈ 6,500 fm, against the exact 7,108.49 fm (8.6% 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 kilometer is bigger than a fathom, so the number of fathoms must come out larger than the number of kilometers. If your answer goes the other way, divide instead of multiplying.
