Convert Kilometers Per Minute to Mach (km/min to M) ▶ Conversion Table
How to convert1 mach (M) = 20.418 kilometer per minute (km/min). Mach (M) is a unit of Speed used in Metric system. Kilometer Per Minute (km/min) is a unit of Speed used in Metric system. Mach numberDefinition of MachMach, commonly denoted M or Ma, is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Austrian physicist and philosopher Ernst Mach, who studied gas dynamics and shock waves. Mach number is used to classify the flow regimes based on the effects of compressibility and shock waves on the flow. How to Convert MachTo convert mach to other units of speed, we need to multiply by the local speed of sound in the medium, which depends on the temperature and pressure of the gas. For example, to convert mach to meters per second, we need to multiply by the speed of sound in air at sea level, which is about 340 m/s. To convert mach to kilometers per hour, we need to multiply by the speed of sound in air at sea level and by 3.6, since there are 3.6 seconds in one hour. Here are some examples of how to convert mach to other units of length in the US Standard system and the SI system:
Where Mach Is UsedMach is used in various fields of science and technology where the speed and direction of movement of objects or phenomena are measured or applied in relation to the speed of sound in the medium. For example:
History of MachThe concept of mach number was first introduced by Swiss engineer Jakob Ackeret in his doctoral thesis in 1929. He proposed it as a convenient way to express the ratio of flow velocity to speed of sound in gas dynamics problems. He also named it after Ernst Mach, who had conducted experiments on supersonic projectiles and shock waves in the late nineteenth century. The term mach number was later popularized by GermanAmerican engineer Theodore von Karman, who used it extensively in his research on aerodynamics and supersonic flight in the early twentieth century. He also established the first supersonic wind tunnel at Caltech in 1939. The first humanmade object to break the sound barrier was a rocketpowered plane called Bell X1 piloted by Chuck Yeager in October 1947. He achieved a speed of about Mach 1.06 at an altitude of 13,000 meters. The fastest unmanned aircraft ever flown was the NASA X43A, which reached a speed of about Mach 9.6 in November 2004. Example Conversions of Mach to Other UnitsHere are some examples of how to convert mach to other units of speed, using the conversion factors given above:
Kilometers per minute: A unit of speedKilometers per minute (km/min) is a unit of speed or velocity in the International System of Units (SI). It measures how fast an object is moving by calculating the distance traveled in kilometers divided by the time taken in minutes. For example, if a train travels 3 kilometers in 2 minutes, its speed is 1.5 km/min. How to convert kilometers per minuteKilometers per minute can be converted to other units of speed or velocity by using simple conversion factors. Here are some common units and their conversion factors:
Where kilometers per minute are usedKilometers per minute are mainly used in transportation and sports to measure the speed or velocity of vehicles and athletes. For example, the maximum speed of a Formula One car is about 5 km/min or about 300 km/h. The average speed of a marathon runner is about 0.35 km/min or about 21 km/h. The cruising speed of a commercial jet airliner is about 16.67 km/min or about 1000 km/h. Definition of kilometers per minuteAccording to the SI definition, one kilometer per minute is the speed of a body that covers a distance of one kilometer in a time of one minute. Mathematically, it can be expressed as:
where v is the speed or velocity in kilometers per minute, s is the distance traveled in kilometers, and t is the time taken in minutes. History of kilometers per minuteThe concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc. The kilometer was originally derived from the French kilometer which was defined as one thousand meters. The minute was originally derived from the Babylonian sexagesimal system which divided an hour into sixty minutes. The combination of these two units resulted in the kilometer per minute as a unit of speed or velocity. The kilometer per minute was officially adopted as part of the SI system in 1960. Example conversions of kilometers per minute to other unitsHere are some examples of converting kilometers per minute to other units of speed or velocity: 1 km/min = 16.6667 m/s = 60 km/h = 37.2823mph = 32.3974kn = 3280.8399 ft/min = 39370.0787 in/min Español Russian Français
