Convert Inches Per Second to Mach (in/s to M) ▶ Conversion Table
How to convert1 mach (M) = 13397 inch per second (in/s). Mach (M) is a unit of Speed used in Metric system. Inch Per Second (in/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:
Inches per second: A unit of speedInches per second ( in/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 inches divided by the time taken in seconds. For example, if a worm travels 2 inches in 1 second, its speed is 2 in/s. How to convert inches per secondInches 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 inches per second are usedInches per second are mainly used in engineering and manufacturing to measure the speed or velocity of machines and processes. For example, the cutting speed of a lathe or a milling machine is often given in inches per minute, which is equivalent to inches per second divided by 60. The rotational speed of a hard disk drive is often given in revolutions per minute, which can be converted to inches per second by multiplying by the circumference of the disk. The flow rate of a fluid through a pipe or a nozzle is often given in gallons per minute, which can be converted to inches per second by multiplying by the crosssectional area of the pipe or the nozzle. Definition of inches per secondAccording to the US customary and imperial systems definition, one inch per second is the speed of a body that covers a distance of one inch in a time of one second. Mathematically, it can be expressed as:
where v is the speed or velocity in inches per second, s is the distance traveled in inches, and t is the time taken in seconds. History of inches per secondThe concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc. The inch was originally derived from the Roman uncia which was one twelfth of a Roman foot or about 0.97 inches . 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 inch per second as a unit of speed or velocity. The inch per second was officially adopted as part of the US customary and imperial systems in the late 18th century.
