About these units
Millimeter/Minute (mm/min)
A millimeter per minute is a slow mechanical speed often encountered in CNC machining, automated laboratory equipment, and controlled industrial processes. In medicine, infusion pumps, surgical robotics, and controlled incisions may specify movement in mm/min to maintain safety and precision. By using millimeters instead of centimeters or meters, the unit ensures fine control in delicate operations where even small deviations matter.
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.
