Quick estimate in your head

For a rough answer, multiply by about 0.3: 400 × 0.3 ≈ 120 m, against the exact 121.92 m (1.6% 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 foot is smaller than a meter, so the number of meters must come out smaller than the number of feet. If your answer goes the other way, divide instead of multiplying.
