## KNOTS to MPH / MPH to KNOTS CONVERTER

## What is KNOTS unit ?

Knots is a unit of speed commonly used in navigation and aviation to measure the speed of a vessel or an aircraft relative to the surrounding air or water. One **knot** is equal to one **nautical mile per hour**, which is approximately 1.852 kilometers per hour (or 1.15078 miles per hour).

The term "nautical mile" refers to a distance of one minute of arc measured along a meridian of the Earth's surface, and is defined as exactly 1,852 meters. The use of knots as a unit of speed is preferred over other units like kilometers per hour or miles per hour in navigation and aviation because it is more directly related to the practical aspects of these fields, such as the time it takes to travel a certain distance, and the speed needed to maintain a safe and efficient course.

## What is MPH unit ?

MPH stands for "**miles per hour**," which is a unit of speed commonly used in the United States and other countries that use the imperial system of measurement. It measures the distance traveled in miles per unit of time, which is typically one hour.

One mile is equivalent to 1.60934 kilometers, so one mile per hour is equivalent to 1.60934 kilometers per hour. The use of MPH is common in road transport, such as measuring the speed of cars, trucks, and other vehicles on highways and roads.

However, in some fields like aviation and marine navigation, knots are used as the primary unit of speed instead of MPH. This is because knots are more directly related to the practical aspects of these fields, such as the time it takes to travel a certain distance and the speed needed to maintain a safe and efficient course over water or air.

## How to convert knots to mph and mph to knots

To convert knots to mph, multiply the speed in knots by 1.15078.

To convert mph to knots, divide the speed in mph by 1.15078.

For example:

- To convert 50 knots to mph: 50 knots x 1.15078 = 57.539 mph (rounded to 3 decimal places).
- To convert 70 mph to knots: 70 mph / 1.15078 = 60.827 knots (rounded to 3 decimal places).

### KNOTS Usage :

Knots are commonly used to measure the speed of aircraft and boats. In aviation, airspeed is typically measured in knots, while ground speed is measured in miles per hour. Similarly, boats and ships often use knots to measure their speed over water. Knots are preferred in these applications because they are a nautical unit of speed and are related to the measurement of distance over water. Additionally, knots are considered more accurate and reliable for navigation purposes, as they are not affected by changes in atmospheric pressure or temperature.

### MPH Usage :

Miles per hour (mph) is a commonly used unit of speed in the United States and some other countries that use the imperial system. It is used to measure the speed of vehicles, such as cars, trucks, and motorcycles, as well as the speed of wind and air flow. In the US, speed limits on roads and highways are typically posted in miles per hour, and vehicle speedometers display speeds in mph. In addition, weather reports often use mph to describe the speed of wind gusts, and wind turbines are rated based on their capacity to generate electricity at specific wind speeds measured in mph. Overall, mph is an important unit of measurement for transportation, weather, and energy-related applications in the US and other countries that use the imperial system.
