About converting Kilometers per Hour to Knots
Kilometers per Hour (km/h) and Knots (kn) are both units of speed, so converting between them is a single multiplication: multiply your Kilometers per Hour figure by 0.54. Ten Kilometers per Hour comes to 5.3996 Knots, and a hundred works out at 53.9957 Knots.
Rule of thumb: going from Kilometers per Hour to Knots divides, so the figure always shrinks — it takes about 1.852 Kilometers per Hour to make a single Knot. If your answer came out bigger, you have the conversion the wrong way round.
What is a Kilometer per Hour?
The kilometer per hour is the road-speed unit of nearly every country on Earth: the number on the speedometer, the number on the sign, the number in the ticket. It is a compound unit rather than a fundamental one — a distance divided by a time — and that is precisely why it took hold, because people already thought in kilometers and in hours and so needed no new idea to think in km/h. Its only real rivals are mph, which clings on in the United States and the United Kingdom, and the knot, which owns the sea and the sky.
What is a Knot?
The knot is one nautical mile per hour, and it is the speed unit of ships and aircraft worldwide no matter what the countries underneath use on their roads. The name is entirely literal: sailors measured speed with a chip log — a weighted board on a rope with knots tied at regular intervals, thrown over the stern and paid out for a fixed time while someone counted the knots running through their hands. It survives because it pairs with the nautical mile, which is one minute of latitude, so speed and chart distance share a ruler. One warning: "knots per hour" is simply wrong. The per-hour is already inside the word.
To put both in perspective: a typical motorway limit is around 120 kilometers per hour, while a cruising airliner does around 470 knots.

Is this Kilometers per Hour to Knots conversion exact?
The definition is exact — Kilometers per Hour and Knots are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
