About these units
Centimeter/Second (cm/s)
A centimeter per second is widely used in hydrology, biology, and physics to measure modest fluid flows, blood velocities, small organism movement, or lab-scale chemical transport. In medicine, cm/s is important in Doppler ultrasound, where blood flow speeds in arteries and veins are routinely measured. In physical sciences, cm/s appears in low-speed fluid mechanics experiments, sediment transport studies, and oceanographic microcurrent analysis. It offers a convenient, human-comprehensible scale for small but dynamic systems.
Mach (20°C, 1 atm) (Ma (20°C))
At 20°C and 1 atmosphere, the speed of sound in air is about 343 m/s, making Mach 1 = 343 m/s under those conditions. Mach numbers classify aerodynamic regimes: Mach 0.3–0.8 (Subsonic), Mach 0.8–1.2 (Transonic), Mach 1–5 (Supersonic), Mach 5+ (Hypersonic). Temperature influences Mach speed significantly; colder air slows sound, while warmer air increases its speed. Aircraft design, jet engines, wind tunnels, aerospace testing, and atmospheric re-entry physics all rely heavily on Mach numbers referenced to standard conditions.
