Quick estimate in your head

For a rough answer, multiply by about 0.03: 18 × 0.03 ≈ 0.54 yd, against the exact 0.5 yd (8.0% 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 inch is smaller than a yard, so the number of yards must come out smaller than the number of inches. If your answer goes the other way, divide instead of multiplying.
