Mach 1 is 761.21 mph.Use this equation to convert Mach to miles per hour: mach x 761.21 = mph
The Mach number for speed is a function of how fast an object is going relative to the speed of sound in that medium (which can vary). The speed of sound at sea level is around 768 mph, so Mach 3.3 at around this level will be 768 x 3.3 = 2534 mph
The Mach number for the speed of an object travelling through a particular medium is the ratio of the object's speed relative to the speed of sound through the same medium. The speed of sound through any medium depends on the nature and density of the medium and, as a result, so does the Mach number. In air, the Mach ratio is mostly dependent on temperature and humidity and, to a lesser extent, on altitude. Generally, Mach 1 (in air, at standard sea level conditions, and at 15 deg C) is approx 1223 kmph. So 3400 kmph would be approx 2.8 Mach. But 3400 kmph in water would be a very much lower Mach number.
Mach 1 is the speed of sound.
Mach 20 is 20 times the speed of sound, which is approximately 767 mph at sea level and room temperature. Therefore, Mach 20 would be 20 x 767 mph, which equals 15,340 mph. This speed is extremely fast and is typically associated with hypersonic flight and reentry vehicles.
Maximum speed: Mach 0.96Operating speed: Mach 0.89
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.

the Mach number
The "Mach number" is the speed of the aircraft as a percentage of the speed of sound. So an aircraft going at Mach 0.74 is traveling at 74% of the speed of sound. (Mach 0.74 is a typical airliner speed.)
No, Mach is a unit of speed used to measure an object's speed relative to the speed of sound in the medium through which it is traveling. For example, Mach 1 is the speed of sound.
Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
0,72 Mach is a subsonic speed. Mach number = speed of an object/speed of sound The speed of sound in dry air at 20 0C is 1 236 km/h.
Mach is the coefficient of the speed of sound, so Mach 1 means you are travelling at 1 x the speed of sound.
Answer Mach 12 Supersonic Speed usually refers to speed just above Mach 1, or as high as Mach 3. Hyper-speed is a higher range but there is no set definition.
That means the speed, compared to the speed of sound. For example, "mach 2" means twice the speed of sound.
