How to convert kilometers per hour to knots
kn = km/h × 0.5399568035Because one knot equals 1.852 kilometers per hour, you can also divide: kn = km/h ÷ 1.852.
A kilometer per hour is smaller than a knot: it takes 1.852 kilometers per hour to make one knot.

About the units
Kilometer per hour (km/h)
The road-speed unit in most of the world. Divide by 3.6 for m/s; 100 km/h is about 62 mph. One kilometer per hour equals 0.2777777778 meters per second (m/s).
Knot (kn)
One nautical mile per hour (about 1.15 mph). The standard speed unit for ships, aircraft and wind reports. One knot equals 0.5144444444 meters per second (m/s).
