What does converting cm/s to Mach represent?

It converts a low-speed measurement into a ratio relative to the speed of sound at 20 °C and 1 atm, helping compare small-scale velocities with aerodynamic flow speeds.

Why is Mach number dimensionless?

Mach is a ratio of an object's speed to the speed of sound at specific reference conditions, so it has no units.

Can this conversion be used for very slow movements?

While possible, very low speeds yield extremely small Mach numbers, which may limit meaningful interpretation due to measurement resolution.
