Converting the other way: knots to feet per second
feet per second = knots × 1.68781. So 4.147387 knots is back to 7 feet per second; one knot is 1.68781 feet per second. See the knots to feet per second table.
Quick estimate in your head
For a rough answer, multiply by about 0.6: 7 × 0.6 ≈ 4.2 kn, against the exact 4.147387 kn (1.3% 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 foot per second is smaller than a knot, so the number of knots must come out smaller than the number of feet per second. If your answer goes the other way, divide instead of multiplying.
About the units
