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.
Yard/Hour (yd/h)
A yard per hour is extremely slow and used only in rare cases where long-term monitoring of tiny movements is necessary—such as soil settlement in construction sites, creeping machinery, or long-term structural drift. Because the yard is an everyday imperial unit, yd/h sometimes appears in engineering logs or legacy datasets, though it is largely replaced by ft/h or mm/h in modern practice. Its use reflects the persistence of imperial measurements in certain specialized contexts.
