Conversion from Kilometers per hour (km/h) to Knot (kn) and vice versa

Updated on by Stefan Banse

Here you can convert the Speed unit Kilometers per hour into the unit Knot and vice versa you can convert Knot into Kilometers per hour. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result, i.e., km/h to kn or kn to km/h. With the following calculator you can also calculate any other Speed unit.

Info about "Kilometers per hour"

Kilometers per hour is used as a standard unit in transportation, therefore it is used in traffic or to measure the travel speed of vehicles. For example, a commercial aircraft flies at a speed of 1,000 km/h then it covers a distance of 1,000 kilometers per hour.

The unit is defined as follows: An object moving at 1 "km/h" per hour will cover one kilometer. "km/h" is approved to use in the international system of units (SI).

Info about "Knot"

Definition: An object that moves with a knot for one hour will cover a distance of one nautical mile. Therefore 1 nautical mile is equivalent to 1,852 meters. A knot refers to the speed of one nautical mile per hour.

The following rule is an easy way to remember when converting knots into km/h: "Multiply by two, and minus 10%". For example, a ship travelling at 20 knots will have a speed around 40-4=36 km/h (exactly 37.04 km/h).

Basis for conversion Kilometers per hour (km/h) to Knot (kn)

The abbreviation for the "Speed unit Kilometers per hour" is km/h. The abbreviation for the "Speed unit Knot" is kn.
