Quick estimate in your head

For a rough answer, multiply by about 1.1: 19 × 1.1 ≈ 20.9 kph, against the exact 20.84832 kph (0.2% 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 per second is bigger than a kilometer per hour, so the number of kilometers per hour must come out larger than the number of feet per second. If your answer goes the other way, divide instead of multiplying.
