What is centimetre per second?

Centimetre per second is a unit of speed used in low-velocity applications such as biological locomotion studies, microfluidics research, and slow-moving mechanical systems.

What is mach (approx at sea level)?

Mach is a dimensionless speed unit expressing the ratio of an object’s speed to the local speed of sound. At sea level, Mach 1 is approximately 343 m/s. It is used in aviation and aerodynamics to characterise high-speed flight regimes.

Worked examples

1 centimetre per second = 0.00002939 mach (approx at sea level)

1 mach (approx at sea level) = 340.29 metre per second

Assumption: Mach uses an approximate sea-level reference (about 340.29 m/s).
