- Start with your value in Kilometers per Hour (km/h).
- Multiply by 0.539957 to perform the conversion.
- The result is your value expressed in Knots (kn).
Conversion Factor
1 km/h = 0.539957 kn
Reverse Factor
1 kn = 1.852 km/h
Worked Example
Convert 25 Kilometers per Hour to Knots: 25 km/h = 13.4989 kn
About Kilometer per Hour (km/h)
A metric unit of speed widely used for road traffic, vehicle speedometers, and transport in every country except the United States and United Kingdom. Also the default unit on GPS devices worldwide and for athletics speed charts in track-and-field. Because 1 km/h = 1/3.6 m/s exactly, conversion between m/s and km/h is trivial — multiply by 3.6 to go from m/s to km/h. Common highway speed limits are 100–130 km/h in most of Europe and Asia.
About Knot (kn)
A unit of speed equal to one nautical mile per hour (about 0.5144 m/s or 1.852 km/h). Knots are the international standard for maritime shipping, recreational boating, weather (wind-speed reports in meteorology), and aviation — pilots worldwide quote airspeed, wind speed, and ground speed in knots because the math of navigation (a nautical mile = one minute of latitude) lines up cleanly with chart work. "Knot" comes from the historical log-line method of measuring ship speed using knotted rope.

Understanding Kilometers per Hour
The Kilometer per Hour (symbol: km/h) is a unit of speed. A metric unit of speed widely used for road traffic, vehicle speedometers, and transport in every country except the United States and United Kingdom. Also the default unit on GPS devices worldwide and for athletics speed charts in track-and-field. Because 1 km/h = 1/3.6 m/s exactly, conversion between m/s and km/h is trivial — multiply by 3.6 to go from m/s to km/h. Common highway speed limits are 100–130 km/h in most of Europe and Asia.
It belongs to the metric measurement system.
Kilometers per Hour are commonly used in automotive engineering, aviation, athletics, and meteorology.
Understanding Knots
The Knot (symbol: kn) is a unit of speed. A unit of speed equal to one nautical mile per hour (about 0.5144 m/s or 1.852 km/h). Knots are the international standard for maritime shipping, recreational boating, weather (wind-speed reports in meteorology), and aviation — pilots worldwide quote airspeed, wind speed, and ground speed in knots because the math of navigation (a nautical mile = one minute of latitude) lines up cleanly with chart work. "Knot" comes from the historical log-line method of measuring ship speed using knotted rope.
Knots are commonly used in automotive engineering, aviation, athletics, and meteorology.
Why Convert Kilometers per Hour to Knots?
Speed conversions between Kilometers per Hour and Knots are frequently needed in automotive engineering, aviation, maritime navigation, and athletics. Speed limits differ by country, wind speed reports vary across weather services, and vehicle specifications are published in region-specific units. Accurate conversion ensures safety and regulatory compliance.
Frequently Asked Questions
How do I convert Kilometers per Hour to Knots?
A metric unit of speed widely used for road traffic, vehicle speedometers, and transport in every country except the United States and United Kingdom. To convert Kilometers per Hour to Knots, multiply by 0.539957. For example, 25 km/h equals 13.4989 kn.
How many Knots are in 1 Kilometer per Hour?
