About Knots to km/h
Convert knots to km/h instantly, with a reference table of common values. The factor is exact: 1 kn = 1.851999692 km/h.
Used to relate a marine or aviation speed to land speeds, since shipping and flying use knots while everything ashore is in kilometres per hour.
A knot is one nautical mile per hour. The name comes from the practice of measuring a ship's speed by paying out a rope with knots tied at regular intervals and counting how many passed in a timed interval. It is the speed unit of shipping and aviation worldwide. Because it derives from the nautical mile, it relates directly to latitude on a chart. A cruising airliner travels at around 500 knots, and a knot is about 1.85 km/h.
Worked through with real numbers: 10 kn is 18.52 km/h, 50 kn is 92.6 km/h, 100 kn is 185.2 km/h.
As for the other side of the conversion: A brisk walk is about 5 km/h, and typical motorway limits sit between 100 and 130 km/h.
Every speed unit is a distance divided by a time, so converting between them means converting the distance and the time together. That is why the factors are less memorable than simple length conversions.
