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 (SI Standard) (Ma)
Mach is a dimensionless measure of speed relative to the speed of sound in a given medium. Mach 1 corresponds to the speed of sound, Mach 2 is twice that speed, and so on. Mach values change with temperature, atmospheric pressure, and altitude because the speed of sound changes with these conditions. Aircraft performance, supersonic flight, rocket design, and shockwave analysis all depend heavily on Mach numbers. Mach is more than just a speed measure—it categorizes aerodynamic regimes: Subsonic (Mach < 1), Transonic (Mach 0.8–1.2), Supersonic (Mach 1–5), Hypersonic (Mach > 5). Mach numbers therefore provide insight into aerodynamic behavior, not just velocity.
