The nautical mile per hour (nmi/h) is a unit of speed that is commonly used in maritime and air navigation. It represents the distance traveled in nautical miles over the course of one hour. One nautical mile is equivalent to one minute of latitude, making it particularly useful for navigation purposes.
The nautical mile is standardized internationally and is defined as exactly 1,852 meters. Therefore, when measuring speed in nautical miles per hour, it is essential to understand that this unit is based on the Earth's geometry, which is crucial for accurate navigation.
The concept of the nautical mile has its roots in ancient navigation, where sailors used the stars and the Earth's curvature to determine their position at sea. Over time, the nautical mile became standardized, and its use in maritime and aviation contexts has evolved to ensure safer and more efficient travel across vast distances.
To convert speed from kilometers per hour (km/h) to nautical miles per hour (nmi/h), you can use the following formula: [ \text{Speed (nmi/h)} = \text{Speed (km/h)} \times 0.539957 ]
For example, if a vessel is traveling at a speed of 20 km/h: [ 20 \text{ km/h} \times 0.539957 = 10.799 \text{ nmi/h} ]
The nautical mile per hour is predominantly used in maritime and aviation industries. It allows for precise navigation and communication between vessels and air traffic control, ensuring that distances and speeds are understood universally.

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:
