What does Mach (20°C, 1 atm) represent?

It is a dimensionless speed ratio comparing an object's speed to the speed of sound in dry air at 20 °C and 1 atm pressure.

Why convert Mach to millimeter per second?

Converting to millimeter per second provides detailed linear speed measurements useful for engineering tasks needing fine spatial resolution.

Can I use this conversion for any air temperature and pressure?

No, this Mach value is specific to conditions at 20°C and 1 atm; changes in atmospheric conditions affect the speed of sound and thus the conversion.
