Converting the other way: kilometers per hour to knots
knots = kilometers per hour × 0.5399568. So 33.336 kilometers per hour is back to 18 knots; one kilometer per hour is 0.5399568 knots. See the kilometers per hour to knots table.
Quick estimate in your head
For a rough answer, multiply by about 1.9: 18 × 1.9 ≈ 34.2 kph, against the exact 33.336 kph (2.6% 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 knot is bigger than a kilometer per hour, so the number of kilometers per hour must come out larger than the number of knots. If your answer goes the other way, divide instead of multiplying.
