About these units
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.
Foot/Hour (ft/h)
A foot per hour is almost comically slow, yet still relevant in specific technical fields. Pipeline corrosion creep, structural deformation, glacial shifts, and certain chemical processes may be measured in ft/h when imperial units are required. While practically invisible to human perception, speeds expressed in ft/h become meaningful over long intervals, providing insight into incremental natural or mechanical change.
