Quick estimate in your head

For a rough answer, multiply by about 6: 400 × 6 ≈ 2,400 ft, against the exact 2,400 ft (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 fathom is bigger than a foot, so the number of feet must come out larger than the number of fathoms. If your answer goes the other way, divide instead of multiplying.
