About these units
Mile/Second (mi/s)
A mile per second is an extraordinarily fast speed—3,600 mph—far beyond any ground vehicle. This unit appears primarily in discussions of orbital mechanics, rocket propulsion, and reentry dynamics. Projectiles in theoretical physics or high-energy impact modeling may also be described in miles per second. The unit's infrequent use reflects its specialized nature, but its dramatic magnitude makes it compelling for illustrating the extremes of velocity attainable in space travel and astrophysics.
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.
