Use this page to convert kilometers per hour into knots. It is useful when land-based or metric weather speeds need to be used in aviation, marine navigation, sailing, or nautical weather contexts.
Kilometers per hour is a land and travel speed unit, while knots are nautical and aviation-focused.
The knot result is smaller than the km/h value because a nautical mile is longer than a kilometer.
This conversion is useful for wind, marine forecasts, aircraft, and vessel speeds.
Use km/h for road and public metric speed; use knots for navigation contexts.
Knots connect speed directly to nautical miles per hour.
This page converts speed, not distance or heading.
Kilometers per hour is familiar for land travel and metric weather reports.
Knots are expected in nautical and aviation settings.
Converting km/h to knots helps reuse metric speed values in contexts where nautical miles matter.
A weather report may publish wind speed in km/h for the general public.
Marine and aviation users often need that same wind speed in knots.
The conversion changes the unit without changing the measured wind or vessel speed.
100 km/h should be about 53.9957 kn.
10 km/h should be about 5.39957 kn.
If 1 km/h becomes 1.852 kn, the conversion direction has been reversed.
Definition: Kilometers per hour measures how many kilometers are traveled in one hour.
History/Origin: Kilometers per hour is widely used for road speeds, travel estimates, and public metric speed reporting.
Current use: kph is used for road speeds, vehicle dashboards, travel estimates, cycling, running, weather, and public-facing metric speed.
Definition: A knot is a speed of one nautical mile per hour.
History/Origin: Knots are used in maritime navigation, aviation, weather reporting, sailing, and ocean-current measurement.
Current use: knot is used for boats, aircraft, wind forecasts, marine navigation, sailing, currents, and nautical-speed references.
| Kilometer per hour [km/h] | Knot [kn] |
|---|---|
| 0.01 km/h | 0.0054 kn |
| 0.1 km/h | 0.053996 kn |
| 1 km/h | 0.539957 kn |
| 2 km/h | 1.079914 kn |
| 5 km/h | 2.699784 kn |
| 10 km/h | 5.399568 kn |
| 20 km/h | 10.799136 kn |
| 50 km/h | 26.99784 kn |
| 100 km/h | 53.99568 kn |
1 km/h = 0.539957 kn
1 kn = 1.852 km/h
Formula: value × 0.539956803546
Example: 15 km/h = 8.099352 kn
Precision note: Use 0.539956803456 knots per kilometer per hour. Round according to the precision expected in the forecast, chart, or navigation tool.
One kilometer per hour is about 0.539956803456 knots.
A knot is one nautical mile per hour.
Use knots for aviation, marine navigation, sailing, nautical weather, and ocean-current contexts.
