Formula
Knots = Kilometers/hour × 0.5399577
Worked Example
Example: 5 Kilometers/hour = 5 × 0.5399577 = 2.69978851 Knots
To convert Kilometers/hour to Knots, multiply the Kilometers/hour value by 0.5399577. This factor is derived from the ratio between the two units.
Kilometers per hour is a unit of speed expressing the number of kilometers traveled in one hour. It is the standard unit for vehicle speed limits and speedometers in most countries worldwide.
History
Kilometers per hour became the standard road speed unit with the widespread adoption of the metric system. Most countries use km/h for speed limits on road signs and vehicle speedometers, with the notable exceptions of the United States, United Kingdom, and Myanmar.
A knot is a unit of speed equal to one nautical mile per hour (approximately 1.151 mph or 1.852 km/h). It is the standard unit of speed in maritime and air navigation worldwide.
History
The term 'knot' comes from the practice of measuring a ship's speed by throwing a log overboard attached to a rope with knots tied at regular intervals. Sailors would count how many knots passed through their hands in a set time. One knot equals one nautical mile per hour.
