About These Units

About Foot/second

Foot per second is a unit of velocity in the imperial system, measuring 0.3048 meters per second. Commonly used in engineering, construction, and physics applications in countries using imperial measurements. This unit is particularly useful for measuring moderate speeds such as projectile velocities, fluid flow rates, and mechanical systems.

About Mach

The Mach is a measure of velocity relative to the speed of sound. The precise speed of sound varies with the density and temperature of the atmosphere, although at 0 °C (at 1atm.) the speed of sound is 331.6 m/s. The mach speed is important to the control of an aircraft, especially at speeds close to or exceeding Mach 1.0. The unit is named after the Austrian physicist Ernst Mach.
