28 Knots To Mph – A knot (/n ɒ t / ) is a unit of speed equal to one nautical mile per hour, or exactly 1.852 km/h (approximately 1.151 miles or 0.514 m/s).
The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), but CT is also common, especially in aviation, and is the format recommended by the International Civil Aviation Organization (ICAO).

This node is used in meteorology, maritime and air navigation. A ship sailing at her 1 knot along the meridian travels about 1 minute in geographic latitude in 1 hour.

The internationally agreed length of a nautical mile is 1852 meters. Previously used the United States, but adopted the international definition in 1954. that. Nautical miles (1853 .248 m).
The United Kingdom, formerly using the British Admiralty nautical mile (6080 feet or 1853 .184 m), adopted the international nautical mile definition in 1970.
Velocity (boat speed and airspeed) relative to the fluid through which a vessel travels is measured in knots. For consistency, navigational fluid velocities (ocean currents, tidal currents, river currents, wind speed) are also measured in knots. Therefore, ground speed (SOG, aircraft ground speed (GS)) and travel speed to distant points (“velocity is good”, VMG) are also expressed in knots.
Until the mid-19th century, ship speed at sea was measured by chip logs. It consists of a wooden panel attached by wires to a coil, weighted at one end so that it floats perpendicular to the surface of the water, so that it is persistent and appreciable against moving water around it. resistance occurs. Chip logs were thrown into the stern of moving ships and the line was allowed to pay.

The knots were tied at a distance of 47 feet 3 inches (14.4018 m) from each other and passed through the finger of the sailor, another sailor using a 30 second hourglass (currently assumed timing is a 28 second hourglass). .
The number of knots is reported and used for Sawmaster dead reckoning and navigation. This method gives a segment value of 20.25 inches per second, or 1.85166 km/h. The difference from the modern definition is less than 0.02%.

The unit knot does not fit into the SI system, but since the nautical mile length on which the unit is based is closely related to the longitude/latitude geographic coordinate system, it is important to preserve that knot in maritime and aviation applications. is. As a result, nautical miles and nautical knots have become the units of interest for use in navigating aircraft and ships.

On standard charts using the Mercator projection, the horizontal (east-west) scale varies with latitude. Nautical charts of the North Atlantic have a two-fold change in scale from Florida to Greenland. Therefore, a single graphic scale, such as that found on many maps, is useless on such charts. In fact, one nautical mile is approximately one minute of latitude, so distances on charts can be easily measured using the scale on the side of the chart and the latitude scale. The Rect British Admiralty chart has a wide central scale to facilitate this ev.
Prior to 1969, the U.S. Federal Aviation Regulations airworthiness standards for commercial aircraft stipulated that distances must be expressed in statutory miles and speeds must be expressed in miles per hour. In 1969, the standard was gradually revised to specify distances in nautical miles and velocities in knots.
The displayed airspeed is close to the actual airspeed only in normal conditions and at low sea level. At an altitude of 11,000 m (36,000 ft), an indicated airspeed of 300 kN corresponds to an actual speed of 500 kN under normal conditions. You may have heard the term knots as the unit used to measure speed in certain modes of transportation. You will often hear knots being used while on a boat.
However, speed measurements are mostly used in modes of transportation that most people don’t commonly use or deal with, such as ships and planes.

Because of this, most people don’t know how fast a knot is, or even what it means. Some people don’t even know knots are used to measure speed.
Especially given that most people are accustomed to using miles per hour and, in some countries, kilometers per hour when measuring speed, it’s no wonder most people don’t know how fast knots are.
This is not surprising because most people either know how to drive or drive much more regularly than they travel by boat or plane.
However, if you’ve traveled by ship or by plane, you’ve probably heard the term knot used. And like most people, if you don’t know exactly how nautical units of measurement work, you’ve probably wondered how fast they are. measurement.

You may also have wondered why miles per kilometer per hour is unacceptable, even though in theory this unit is much more reasonable.
So if you’ve had any of these questions before and want to know how fast your package is, what knots it uses, and how fast it compares to other units of measurement, this article is for you. Please read on.
You may hear the knot called by other names, but the most common is he 1 nautical mile/hour. But in this case the question inevitably arises: how long is a nautical mile, and what is the difference between a standard mile and a nautical mile?
The definition of a nautical mile, therefore, is the distance or latitude minute between two points on her on Earth, compared to the law mile, about 1.15 law mile, or 1.15078 is used for exact calculations.

Because of this, calculating the difference between knots and miles per hour is actually pretty easy. Simply multiply knots by 1.15 to get miles per hour.
As an example of this, if you are on a boat traveling at 20 knots, multiply 20 by 1.15 for her to get 23, so a boat traveling at 20 knots will have her traveling at 23 miles. . time.
For example, if the speed of 1 mph is expressed as MPH, and you want to know how knots are expressed, knots are expressed using KN. A normal cruise ship would find her traveling at a speed of 21-23 knots. That’s about 24-26 mph using the previous calculator.
Some ships are slow, some are fast, but in general this is as fast as a ship.
The Sailing Trifecta
Since there is not much difference between knots and miles per hour, you may be wondering why knots are used in the first place, what is it?
In case you didn’t know, the knot is actually a very historical unit whose origins date back to his 17th century. It was originally used by sailors of this era as a way of estimating sailing speed.
To measure this, use a piece of wood commonly called a log. Next, attach a rope with knots at regular intervals to the log.
It is then left for a period of time, usually recorded with an hourglass, and after the time has elapsed, simply counting the number of knots that reach the sea. nuts. Because of this old way of counting speed, the term was adopted when measuring nautical miles.
Knots To Miles Per Hour Conversion (kn To Mph)
Of course, it’s worth pointing out that the 17th century system wasn’t particularly centralized, and didn’t have one particular way of counting knots. So the term was at some point changed to be used to describe speed in nautical miles. Complete in 1 hour.
The main reason ships use the knots speed system so often is because there are specific speeds associated with nautical miles. Of course, nautical miles are much more commonly used than standard nautical miles when traveling by sea.
When traveling by ocean, it makes sense to use nautical miles, which are measured using knots, since you don’t use the system used to travel land miles.
While on a boat, you may hear staff refer to speed using miles per hour, but this is usually done for passengers who want a more readable way of communicating speed.
