About these units
Yard/Minute (yd/min)
A yard per minute is used in sports coaching, physical training, and some industrial processes. Coaches may track a swimmer's or runner's speed informally using yards per minute, especially in regions where yard-based pools or tracks still exist. Certain fabric and material-feed systems also use yd/min to specify production speed, as textiles and printing industries historically measured length in yards. The unit bridges athletic training and industrial applications in imperial-unit contexts.
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.
