About Speed Converter
Speed units combine a distance and a time, so their factors come from dividing one by the other. One kilometer per hour is 1000 meters divided by 3600 seconds, or about 0.2778 meters per second.
The knot is the odd one out. It is one nautical mile per hour, and a nautical mile is 1852 meters - originally one minute of latitude - which makes a knot roughly 1.852 km/h and keeps it useful for navigation.
