Historical Note on FPS
The FPS system is rarely seen 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.

The imperial system, upon which it was based, continues to be used in domestic commerce and trade in some parts of the world.
