The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower).
An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure).
BUT
In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.

Mach speed is how many miles?
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
How fast in in Mach would you have to go to make it 442 miles in one minute?
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
What is mach 4 speed?
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
What is the mach 1 top speed?
Mach 1 means the speed of sound. The speed of sound is 343meters per second, 1,126ft/sec or 768mph.
If the plane is travelling at match1 this means it is travelling at speed?
Match1? No clue. But you are probably referring to MACH 1, which is the speed of sound in air, roughly 340 m/s depending on air temperature. Mach 2 would be twice the speed of sound, mach 3 three times, etc.
How tall is Frantisek Mach?
Frantisek Mach is 6' 1 1/2".
How fast is Mach 1 Mach 2 Mach 3 Mach 4 etc to the fastest Mach level on record?
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.
What is the highest speed airplane?
If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
What is the plural of mach?
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.

What do you mean when you say that the Concorde can travel at mach 2?
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
Mach speed is how many miles?
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
What are the release dates for Wakusei robo Dangard A - 1977 Down from Mach 2 1-2?
Wakusei robo Dangard A - 1977 Down from Mach 2 1-2 was released on: USA: 1980
What does Mach 25 mean?
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.
What is meant by machnumber?
Mach is a measure of speed based on the speed of sound at sea level. Mach 1 = 642 MPH . Mach 2 = 2 x 642 MPH or 1284 MPH.
What is mark1?
Maybe you mean Mach 1 - which is the speed of sound. Mach 2 is twice the speed of sound, and so on ...
