How the conversion works
Multiply by 1.852 to go from knot to kilometer per hour, 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? kilometer per hour to knot: 1 km/h = 0.5399568035 kn.
