About these units
Yard/Second (yd/s)
A yard per second is a moderately fast speed, equal to 3 ft/s or 0.9144 m/s, used in some athletic contexts—particularly American football or sprinting analysis. It provides an intuitive measure for sports where yard-based distances dominate. Because the unit aligns with common field dimensions, it simplifies performance evaluation in training and gameplay. The yard per second reflects the enduring influence of imperial measurements in American athletics.
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.
