How the conversion works
Multiply by 0.2777777778 to go from kilometer per hour 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 kilometer per hour: 1 m/s = 3.6 km/h.
