Mach is the speed of sound in that medium, and is known as Mach 1. It will vary according to pressure and temperature. [More correctly, it is the dimensionless number relating the speed of an object to that of sound in that medium.] Mach does not have units associated with it, such as mph or kmph.
I believe it is the speed of sound: 340.19 m/s
The speed of sound.
Mach 3.5 is about 2,664 mph
Mach 1 (or the speed of sound) is 1,225km per hour Mach 75 is there for 91,875 km/h
the Mach number
Mach 889 is about 659,233 mph
Mach 1.4 = 1066mi/h (rounded)
yes
Knots or Mach for very fast ones
Basic: Mach is a measurement of the speed of sound in air. Therefore, mach6 is six times the speed of sound in air.761.2 * 6 = 4,567.2 mile/hour (mph)More in depth:"Mach" is a relative measurement of speed and fluid temperature.Here are some examples of Mach 6:Mach 6 at sea level (0 feet) is 4,567.3 mph (CAS) and 4,567.3 mph (TAS)Mach 6 at FL 50 (Flight Level 50,000) is 3,147.97 mph (CAS) and 3,960.31 mph (TAS)CAS = Calibrated Air Speed. The speed which a instrument in the plane would show.TAS = True Air Speed. The actual speed of the object relative to the medium it is traveling in.
Knots is a measurement of speed. Horsepower is a measurement of power. To obtain that speed on water is probably not possible. To obtain that speed in air takes allot of horsepower. That is over Mach 2 (twice the speed of sound),
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
Maximum speed: Mach 0.96Operating speed: Mach 0.89
Mach 2.
To mach for you if you cant spell it.
Ernst Mach .
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.
