Definition:FPS

Definition
FPS is the foot-pound-second standard system of units of measurement.

It is otherwise known as the imperial system, and was used throughout the British Empire until the mid-20th century.

It is not much used nowadays, as most nations have converted to the SI system based on the metre-kilogram-second base units.

As there are several systems similar to this one, some of which use the same name for subtly different standard units, the use of SI units is strongly encouraged.
