The foot-pound-second (FPS) system is the usual unit system used in the U.S. whendealing with physics.Over the years there have been movements to standardize units so that all countries, includingthe United States, will adopt the SI system. The SI system is made up of two related systems,the meter-kilogram-second (MKS) system and the centimeter-gram-second (CGS) system.The MKS and CGS systems are much simpler to use than the English system because they usea decimal-based system in which prefixes are used to denote powers of ten. For example, onekilometer is 1000 meters, and one centimeter is one one-hundredth of a meter. The Englishsystem has odd units of conversion. For example, a mile is 5280 feet, and an inch is one twelfthof a foot.
