How to convert Knots to Meters per second
To convert knots to meters per second, multiply by 0.514444. One knot equals 0.514444 m/s, and one meter per second equals 1.943844 kn.
- Take the value in knots — for example 7.5 kn.
- Multiply by 0.514444 (the number of meters per second in one knot).
- 7.5 × 0.514444 = 3.858333 m/s.
Quick mental estimate: Divide the number of knots by 1.94 (within 0.2% of the exact answer).
