How many kilometers per hour is HNA?

1 knot = 1 knot =1.852km/h = 0.514444m/s.

For example, 60 sections are 60 times1852 =11120m/h.

Unit symbol: kn.

Land vehicles, as well as inland river vessels, usually take kilometers (kilometers)/hour as the unit, while the speed unit of marine vessels (including warships) is called "knots".

Later, it was also used to express the speed of wind and ocean currents. The symbol of the festival is the prefix of "knot" in English, which is represented by "kn". 1 knot is equal to 1 nautical mile per hour, that is to say, driving 1.852 kilometers (kilometers) per hour.

In navigation, the unit for measuring short distances is "chain", and the chain of 1 is equal to110 nautical mile. The code is the prefix of English "Cable", with "cab".

In addition, this section is also the length unit mark for the manufacture and use of ship anchor chain links. Generally, the anchor chain length of 27.5m is 1 knot, while the anchor chain length mark of China ships is 1 knot with 20m.

The origin of "festival":

As early as16th century, maritime navigation was quite developed, but there were no clocks or nautical recorders at that time, so it was difficult to accurately determine the sailing speed of the ship. However, a clever sailor came up with a wonderful method. When the ship is sailing, he throws a floating body with a rope into the sea, and then calculates the speed of the ship according to the length of the rope pulled out in a certain period of time.

The time at that time was still measured by quicksand timer. In order to calculate the speed of the ship more accurately, sometimes the rope is very long, so many knots are tied at the equal distance of the rope, so that the whole speed measuring rope is divided into several sections. As long as the number of knots dragged by the rope in the same unit time is measured, the corresponding speed can naturally be measured.

As a result, "knot" has become a unit of measurement for the speed of seagoing ships; Correspondingly, the speed measuring units of underwater weapons such as seawater velocity, offshore wind speed and torpedo are widely used in the world.

The code name of "Knot" is the prefix of English "Knot", which is represented by "Kn". 1 knot is equal to 1 nautical mile per hour, that is to say, driving 1.852 kilometers (kilometers) per hour. In navigation, the unit for measuring short distances is "chain", and the chain of 1 is equal to110 nautical mile. The code is the prefix of English "Cable", with "Cab".
