About these units
Knots (kn): A knot is one nautical mile per hour, exactly 1.852 km/h. Ships, aircraft and wind speeds at sea use knots.
Kilometers per Hour (km/h): Kilometres per hour (km/h) is the speed unit on road signs and speedometers in most of the world.
Frequently asked questions
How many kilometres per hour are in 1 knot?
1 knot equals 1.852 kilometres per hour (km/h).
How do I convert kn to km/h?
Multiply the value in knots by 1.852. For example, 5 kn × 1.852 = 9.26 km/h.
How do I convert kilometres per hour back to knots?
Multiply by 0.5399568035 (or divide by 1.852). 1 km/h = 0.5399568035 kn.
What is a knot?
A knot is one nautical mile per hour, exactly 1.852 km/h. Ships, aircraft and wind speeds at sea use knots.
