About these units
Meter/Minute (m/min)
A meter per minute reflects slow but practical speeds for human or mechanical movement. At 1 m/min, motion is deliberate and controlled—appropriate for precision machining, automated stage equipment, or calibration systems. In exercise science, treadmill incline adjustments, warm-up activity, and walking machines may use m/min for exact gait-speed research. The simplicity of dividing by minutes rather than hours makes the unit useful for short-interval calculations in engineering and ergonomics.
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.
