foot per second
Speedexact by definition
The foot per second is exactly 0.3048 m/s, following from the exact definition of the foot. It is used in American ballistics, open-channel hydraulics and machine design, where velocities are naturally sized in feet. The factor is exact by definition.
Watch out: Sixty miles per hour is exactly 88 ft/s, a conversion worth memorising because it is exact rather than approximate.
