Quick estimate in your head

For a rough answer, multiply by about 0.0009: 400 × 0.0009 ≈ 0.36 km, against the exact 0.36576 km (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 yard is smaller than a kilometer, so the number of kilometers must come out smaller than the number of yards. If your answer goes the other way, divide instead of multiplying.
