Feet per second to Mach Converter

To convert a measurement in feet per second to mach, multiply the value by 0.000895706603. The conversion factor comes from the relationship between both units and the meter per second.

For example, to convert 5 ft/s to mach: 5 × 0.000895706603 = 0.004478533016 Ma.

The foot per second is an imperial unit of speed equal to one foot traveled in one second, or exactly 0.3048 meters per second. Ft/s is common in US engineering and ballistics, where distances are measured in feet. Muzzle velocities, fluid flow, and free-fall speeds are frequently expressed this way.

Common uses of feet per second include: Ballistics and muzzle velocity; US engineering and fluid flow; Free-fall and projectile physics; Conveyor and belt speeds.

Mach is the ratio of an object's speed to the local speed of sound. Mach 1 at sea level and 15°C is about 340.29 meters per second. Named after physicist Ernst Mach, the Mach number became essential in aeronautics as aircraft approached and exceeded the speed of sound in the mid-20th century.

Common uses of mach include: Aircraft and jet speed ratings; Aerodynamics and wind-tunnel testing; Supersonic and hypersonic research; Missile and projectile speed specs.

Here are some common values converted:
