Why is Mach (20°C, 1 atm) considered dimensionless?

Mach (20°C, 1 atm) is defined as the ratio of an object's speed to the speed of sound under standard conditions, so it is a relative and dimensionless quantity.

When should I use meter per hour as a speed unit?

Meter per hour is useful for expressing very slow linear speeds, such as mechanical feed rates or structural displacement over an hourly period.

Can this converter be used for speeds at different temperatures or pressures?

No, the conversion assumes speeds relative to the speed of sound at 20°C and 1 atm specifically.
