The mile per hour (mph) is a unit of speed commonly used in the United States and the United Kingdom. It quantifies the distance traveled in miles over the duration of one hour. This measurement is particularly relevant in transportation and travel, where understanding speed is crucial for safety and efficiency.
The mile per hour is standardized under the imperial system, where one mile is equivalent to 1,609.34 meters. This unit is widely recognized and utilized in various contexts, including road signs, vehicle speedometers, and aviation.
The concept of measuring speed dates back to ancient civilizations, but the mile as a unit of distance has its roots in Roman times. The mile was initially defined as 1,000 paces of a Roman soldier. Over time, the mile evolved, and the mile per hour became a standard unit for measuring speed, particularly in the context of land and air travel.
To convert 100 miles per hour to kilometers per hour, you can use the following formula: [ \text{Speed in km/h} = \text{Speed in mph} \times 1.60934 ] For example: [ 100 \text{ mph} \times 1.60934 = 160.934 \text{ km/h} ]
Mile per hour is predominantly used in the United States for speed limits on roads and highways. It is also employed in various sports and activities, such as running and cycling, to gauge performance and speed.

The Mach unit, represented by the symbol M, is a dimensionless measure of speed defined as the ratio of the speed of an object to the speed of sound in the surrounding medium. It is a crucial metric in fields such as aerodynamics, aerospace engineering, and fluid dynamics, where understanding the relationship between an object's speed and the speed of sound is essential.
Mach is standardized based on the speed of sound, which varies with temperature and pressure. At sea level and at a temperature of 20 degrees Celsius, the speed of sound is approximately 343 meters per second (1,125 feet per second). The Mach number is calculated by dividing the speed of the object by this standard speed of sound.
The concept of Mach was introduced by the Austrian physicist Ernst Mach in the late 19th century. His work on shock waves and supersonic speeds laid the foundation for modern aerodynamics. Over the years, the Mach number has become a fundamental parameter in the design and analysis of aircraft and rockets, enabling engineers to predict performance and behavior at various speeds.
To illustrate the use of the Mach number, consider an aircraft traveling at a speed of 680 miles per hour. To convert this speed to Mach, we first convert miles per hour to meters per second (1 mph ≈ 0.44704 m/s):
680 mph ≈ 303.9 m/s.
Next, we divide the speed of the aircraft by the speed of sound at sea level:
Mach = Speed of Aircraft / Speed of Sound = 303.9 m/s / 343 m/s ≈ 0.886 M.
Thus, the aircraft is traveling at approximately 0.886 Mach.
The Mach number is widely used in various applications, including:
