Converting Mach to Foot per Sec is a common speed conversion. One mach (M) equals 1,116 foot per sec (ft/s). Mach numbers express speed relative to the speed of sound, used in aviation and aerospace.
This conversion is commonly needed for sailing and marine navigation, physics and engineering calculations, driving and speed limit compliance. Feet per second are used in ballistics, engineering, and some US speed calculations.
To put mach in perspective: the speed of sound (Mach 1). In foot per sec, common references include the speed of sound (about 1,125 ft/s).
Mach numbers are named after Austrian physicist Ernst Mach. The exact speed of Mach 1 varies with temperature and altitude.
Feet per second is commonly used in ballistics to describe projectile muzzle velocity, giving more intuitively sized numbers than meters per second for that range of speeds.
