## How to convert miles per hour to knots (mph to kn, kt)

The formula for converting miles per hour to knots is: kn, kt = mph × 0.868976241918425. To calculate the mile per hour value in knots first substitute the mile per hour value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 mile per hour in knots we follow these steps:

kn, kt = mph × 0.868976241918425

kn, kt = 1 × 0.868976241918425

kn, kt = 0.868976241918425

In other words, 1 mile per hour is equal to 0.868976241918425 knots.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 5 miles per hour to knots is:

1. Understand the conversion formula: kn, kt = mph × 0.868976241918425
2. Substitute the required value. In this case we substitute 5 for mph so the formula becomes: kn, kt = 5 × 0.868976241918425
3. Calculate the result using the provided values. In our example the result is: 5 × 0.868976241918425 = 4.344881209592125 kn, kt

In summary, 5 miles per hour is equal to 4.344881209592125 knots.

## Converting knots to miles per hour

In order to convert the other way around i.e. knots to miles per hour, you would use the following formula: mph = kn, kt × 1.150779448. To convert knots to miles per hour first substitute the knot (std) value into the above formula, and then execute the calculation. If we wanted to calculate 1 knot (std) in miles per hour we follow these steps:

mph = kn, kt × 1.150779448

mph = 1 × 1.150779448

mph = 1.150779448

Or in other words, 1 knot (std) is equal to 1.150779448 miles per hour.

## Conversion Unit Definitions

### What is a Mile Per Hour?

Mile per hour (abbreviated as mph) is a unit of speed commonly used in countries that follow the imperial system of measurement, such as the United States and the United Kingdom. It measures the distance traveled in miles divided by the time taken in hours.
The mile, which is the primary unit in this measurement, is an imperial unit of length equal to 5,280 feet or approximately 1.609 kilometers. It originated from ancient Roman measurements and has been widely adopted in various English-speaking countries.
The hour, the unit of time in this measurement, is a standard unit of time equal to 60 minutes or 3,600 seconds. It is used to quantify the duration of an event or the time taken to travel a certain distance.
To better understand mile per hour, let's consider an example. Imagine a car traveling at a constant speed of 60 mph. This means that for every hour, the car covers a distance of 60 miles. In practical terms, if the car maintains this speed for 4 hours, it would have traveled a total distance of 240 miles.
Mile per hour is widely used to measure the speed of vehicles, such as cars, motorcycles, trucks, and airplanes, on roads, highways, and runways. Speed limit signs, traffic reports, and vehicle speedometers often display speeds in miles per hour.
It's important to note that mile per hour is not the sole unit of speed used globally. Many countries, particularly those that follow the metric system, use kilometers per hour (km/h) as their primary unit of speed. Conversion between mile per hour and kilometer per hour can be done using the conversion factor of approximately 1.609.
In summary, mile per hour is a unit of speed used in countries that follow the imperial system of measurement. It represents the distance traveled in miles divided by the time taken in hours and is commonly used to measure the speed of vehicles. Understanding and converting between different speed units, such as mile per hour and kilometer per hour, is essential for international travel and communication.

### What is a Knot (std)?

A knot is a unit of speed typically used in maritime and aviation contexts. It represents one nautical mile per hour, where a nautical mile is defined as one minute of latitude on a navigational chart. Knots are commonly used to measure the speed of ships, boats, and aircraft.
To provide a detailed example of knots, let's consider a sailboat traveling in the ocean. If the sailboat covers a distance of 10 nautical miles in one hour, then its velocity would be 10 knots. This means that the sailboat is moving at a speed of 10 knots.
Knots are especially important in navigation and maritime operations. They allow sailors and ship navigators to measure the speed of a vessel relative to the water it is traveling in. Since nautical miles are based on the Earth's latitude, knots provide a consistent and reliable measurement of speed regardless of location.
In aviation, knots are also commonly used to measure the speed of aircraft. Airspeed indicators in airplanes often display the speed in knots. This information helps pilots assess the performance of the aircraft, maintain safe speeds, and communicate with air traffic control.
It's worth noting that knots can be converted to other units of speed. One knot is equal to approximately 1.15078 statute miles per hour (mph) or 1.852 kilometers per hour (km/h).
In summary, a knot is a unit of speed that represents one nautical mile per hour. It is widely used in maritime and aviation contexts to measure the speed of ships, boats, and aircraft. Knots provide a consistent and standardized measurement of speed relative to nautical miles and play a crucial role in navigation, safety, and communication in these domains.
