About these units
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.
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.
