Convert Mach to multiples of the speed of sound. Mach 1 equals exactly 1x the speed of sound.
Mach number is defined as the ratio of speed to the speed of sound. Mach 1 equals exactly 1 times the speed of sound, so the conversion is 1:1.

Yes, the Mach number is the ratio of speed to the local speed of sound. Mach 1 = 1x speed of sound.
Mach is a dimensionless ratio, while speed of sound has a specific value that changes with conditions. They are conceptually equivalent.
Yes. The speed of sound depends on temperature and medium. At sea level (15C) it is about 343 m/s; at altitude it decreases.
Mach 2 is exactly 2 times the speed of sound.
