Mach (Ma) to Feet per second (ft/s) Conversion
Mach
The Mach number represents the ratio of an object's speed to the local speed of sound. Mach 1 is approximately 343 m/s (1,235 km/h) at sea level and 20 °C, but varies with temperature and altitude. Named after Austrian physicist Ernst Mach, the Mach number is fundamental in aerodynamics: subsonic is below Mach 0.8, supersonic from Mach 1.2 to 5, and hypersonic above Mach 5.
Feet per second
Feet per second (ft/s) is a unit of speed in the US customary and imperial systems equal to approximately 0.3048 m/s or 1.09728 km/h. It is commonly used in ballistics to express projectile velocities, in structural engineering for wind speed calculations, and in sports science. The speed of sound at sea level is approximately 1,125 ft/s (343 m/s), a reference used in firearms and aeronautics.
