Kilometers Per Hour to Knots Conversion
Enter the speed in kilometers per hour below to get the value converted to knots.
How to Convert Kilometers Per Hour to Knots
To convert a kilometer per hour measurement to a knot measurement, multiply the speed by the conversion ratio.
Since one kilometer per hour is equal to 0.539957 knots, you can use this simple formula to convert:
The speed in knots is equal to the kilometers per hour multiplied by 0.539957.
Kilometers per hour and knots are both units used to measure speed. Keep reading to learn more about each unit of measure.
Kilometers Per Hour
Kilometers per hour are a measurement of speed expressing the distance traveled in kilometers in one hour.
The kilometer per hour, or kilometre per hour, is an SI unit of speed in the metric system. Kilometers per hour can be abbreviated as km/h, and are also sometimes abbreviated as kph. For example, 1 kilometer per hour can be written as 1 km/h or 1 kph.
In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.[1]
Kilometers per hour can be expressed using the formula:
vkm/h = dkmthr
The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.
Knots
One knot is equal to a speed of one nautical mile per hour,[2] or one minute of latitude per hour.
Knots can be abbreviated as kn, and are also sometimes abbreviated as kt. For example, 1 knot can be written as 1 kn or 1 kt.
