Mach (SI Standard) (Ma)
Mach is a dimensionless measure of speed relative to the speed of sound in a given medium. Mach 1 corresponds to the speed of sound, Mach 2 is twice that speed, and so on. Mach values change with temperature, atmospheric pressure, and altitude because the speed of sound changes with these conditions. Aircraft performance, supersonic flight, rocket design, and shockwave analysis all depend heavily on Mach numbers. Mach is more than just a speed measure—it categorizes aerodynamic regimes: Subsonic (Mach < 1), Transonic (Mach 0.8–1.2), Supersonic (Mach 1–5), Hypersonic (Mach > 5). Mach numbers therefore provide insight into aerodynamic behavior, not just velocity.
Foot/Minute (ft/min)
A foot per minute is common in industrial engineering, HVAC air flow analysis, elevator design, and manufacturing processes. Ventilation rates in ducts are often reported in ft/min, making the unit crucial for designing safe and comfortable living spaces. In machining, ft/min corresponds to cutting speed along a tool edge, helping determine tool wear and material removal rates. Despite being less familiar in daily life, ft/min is a key engineering unit.
