How to convert1 mach (M) = 0.211444444 mile per second (mi/s). Mach (M) is a unit of Speed used in Metric system. Mile Per Second (mi/s) is a unit of Speed used in Standard 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:
Miles per second: A unit of speedMiles per second (mi/s) is a unit of speed or velocity in the US customary and imperial systems. It measures how fast an object is moving by calculating the distance traveled in miles divided by the time taken in seconds. For example, if a bullet travels 1 mile in 0.5 seconds, its speed is 2 mi/s. How to convert miles per secondMiles per second 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 miles per second are usedMiles per second are mainly used in physics and astronomy to measure the speed or velocity of very fast objects and phenomena. For example, the escape velocity of the Earth is about 11 km/s or about 6.84 mi/s. The orbital velocity of the Earth around the Sun is about 30 km/s or about 18.64 mi/s. The speed of light in a vacuum is about 300000 km/s or about 186282 mi/s. The speed of sound in air at sea level is about 343 m/s or about 0.213139 mi/s. Definition of miles per secondAccording to the US customary and imperial systems definition, one mile per second is the speed of a body that covers a distance of one mile in a time of one second. Mathematically, it can be expressed as:
where v is the speed or velocity in miles per second, s is the distance traveled in miles, and t is the time taken in seconds. History of miles per secondThe concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc. The mile was originally derived from the Roman mile which was defined as one thousand paces or about 5000 Roman feet. The second was originally defined in terms of the Earth’s rotation as one eightysix thousand four hundredth of a mean solar day. The combination of these two units resulted in the mile per second as a unit of speed or velocity. The mile per second was officially adopted as part of the US customary and imperial systems in the late 18th century.
