The knot per second (kn/s) is a unit of velocity that measures speed in nautical miles per hour. It is commonly used in maritime and aviation contexts, where it is essential to understand the speed of vessels and aircraft relative to the water or air. One knot is equivalent to one nautical mile per hour, which is approximately 1.15078 miles per hour.
The knot is a standardized unit of measure recognized internationally. The International System of Units (SI) does not include the knot as a base unit; however, it is widely accepted in navigation and meteorology. The symbol for knot is "kn," and when expressed in terms of seconds, it becomes "kn/s."
The term "knot" originates from the practice of measuring a ship's speed by counting the number of knots tied in a rope that was thrown overboard. This method dates back to the 17th century and has evolved into the modern use of the knot as a unit of speed. The adoption of the knot in aviation and maritime navigation has made it an essential component of global transportation.
To convert speed from knots to kilometers per second, you can use the following formula:
1 kn = 0.000514444 km/s
For example, if a vessel is traveling at 20 knots, the calculation would be:
20 kn × 0.000514444 km/s = 0.01028888 km/s
Knot per second is primarily used in maritime and aviation contexts. It helps navigators and pilots understand their speed relative to the earth's surface, which is crucial for safe and efficient travel. Whether you're sailing a boat or flying an aircraft, knowing your speed in knots can help you make informed decisions.

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:
To use the Mach Converter Tool, follow these simple steps:
What is the Mach number? The Mach number is a dimensionless unit that represents the ratio of an object's speed to the speed of sound in the surrounding medium.
How do I convert miles per hour to Mach? To convert miles per hour to Mach, divide the speed in mph by the speed of sound at the given conditions (approximately 343 m/s at sea level).
Why is the Mach number important in aviation? The Mach number helps engineers and pilots understand an aircraft's performance relative to the speed of sound, which is critical for safety and efficiency.
Can I use the Mach Converter Tool for different units of speed? Yes, our Mach Converter Tool allows you to convert various units of speed, including kilometers per hour and meters per second, to Mach.
What factors affect the speed of sound? The speed of sound is influenced by temperature, pressure, and the medium through which it travels (e.g., air, water).
