Converting Foot per Sec to Mach is a common speed conversion. One foot per sec (ft/s) equals 0.000895706603 mach (M). Feet per second are used in ballistics, engineering, and some US speed calculations.
This conversion is commonly needed for sailing and marine navigation, physics and engineering calculations, driving and speed limit compliance. Mach numbers express speed relative to the speed of sound, used in aviation and aerospace.
To put foot per sec in perspective: the speed of sound (about 1,125 ft/s). In mach, common references include a commercial jet (about Mach 0.85).
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.
Mach numbers are named after Austrian physicist Ernst Mach. The exact speed of Mach 1 varies with temperature and altitude.
