How the conversion works
Multiply by 0.5144444444 to go from knot to meter per second, or divide by it to go back. Every conversion on this site routes through the SI value (m/s) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? meter per second to knot: 1 m/s = 1.943844492 kn.
