Quick estimate in your head

For a rough answer, multiply by about 1.9: 400 × 1.9 ≈ 760 kn, against the exact 777.537797 kn (2.3% 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 meter per second is bigger than a knot, so the number of knots must come out larger than the number of meters per second. If your answer goes the other way, divide instead of multiplying.
