Quick estimate in your head

For a rough answer, multiply by about 70: 4 × 70 ≈ 280 in, against the exact 288 in (2.8% 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 inch, so the number of inches must come out larger than the number of fathoms. If your answer goes the other way, divide instead of multiplying.
