Knots to Meters per Second (kn to m/s) Converter
1 knot (kn) = 0.514444 meters per second (m/s). To convert knots to meters per second, multiply by 0.514444: 20 kn × 0.514444 = 10.2889 m/s. Also searched as knots to metres per second.
Quick facts
- 1 kn = 0.514444 m/s
- 1 m/s = 1.94384 kn
- Formula: m/s = kn × 0.514444
- Quick estimate: multiply by about 0.51
How to convert knots to meters per second
- Take the value in knots.
- Multiply it by 0.514444 (the number of meters per second in one knot).
- Round the result to the precision you need.
Worked example (a ferry's cruising speed): 20 kn × 0.514444 = 10.2889 m/s.
To convert meters per second back to knots, multiply by 1.94384, or divide by 0.514444.
