About these units
Centimeter/Minute (cm/min)
A centimeter per minute is a very slow but measurable speed, ideal for documenting the movement of small mechanical devices, capillary flow, microfluidics, or slow conveyor systems. Medical applications include infusion pump rates, which may sometimes be described in cm/min when relating to catheter insertion or microdroplet transport speed. Because centimeters align with everyday physical intuition, this unit strikes a balance between precision and accessibility in niche scientific applications.
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.
