If you're a fan of the SI unit system, you will probably measure it in newton-meters. To keep like measurements together, physicists and mathematicians have grouped them into measurement systems. The foot–pound–second system or FPS system is a system of units built on three fundamental units: the foot for length, the (avoirdupois) pound for either mass or force (see below), and the second for time. foot/second2.History/origin: The pound-force is part of the foot-pound-second (FPS) system of units. → M o r e a b o u t F P S s y s t e m : It is the british engineering system of units which uses foot as the usnit of length, pound as the unit of mass and second as the unit of time resectively. Unfortunately, the obsolete cgs (centimeter-gram-second) system and the even more obsolete fps (foot-pound-second) system are still in use today, although their continued employment is now strongly discouraged in science and engineering (except in the US!). Ishida Europe. The equivalent SI unit is the metre per second. 1 570. ft/s2 = 0.138254954376 N (precisely). By Steven Holzner . The technical or gravitational FPS system, is a coherent variant of the FPS system that is most common among engineers in the United States. 1 lb/in 3. To create a standard procedure, scientists are developing another system of unit called System de International or S.I in the year 1960. It takes the pound-force as a fundamental unit of force instead of the pound as a fundamental unit of mass. The unit of mass in FPS system is Pound. The complex unit of speed and derived unit of force are the foot per second and poundal, respectively, where 1 poundal equals 1 foot pound per second squared. Practical unit of electric potential and electro motile force of cell. 454 kg accelerated with 9.8 m/sec^2 acceleration. In the FPS system of units, the unit of mass is pound or lb, and the unit of acceleration is feet per second squared or ft/s². 1ft = 0,3048 m; 1 GPM = .00223 CFS. If, however, you use the FPS (foot-pound-second) system, you might be more familiar with the unit of foot-pounds. FPS TO METRIC. Second. The acceleration of 32.1740 ft/sec 2 is approximately the value of the earth's gravitational acceleration at 45 degrees north latitude. Gravitation unit of force in F.P.S system. AB-2012 FPS Abrasion Tester can perform tests by controlling tangential force between the test piece and the road wheel in addition to the conventional control of slip ratio, aiming more correlation to the real tires. It is denoted as lbf. YouTube Encyclopedic. Unit of length in expressing X-ray waves –lengths. The unit of mass is a pound (Lb). Abbreviations include ft/s, ft/sec and fps. In the foot-lb-sec (FPS) system, an appropriate unit would be cubic feet per second (CFS). Example. *fps - system: foot pound second-system. X-unit (X.U.) Technical Information. [1], Physical system of measurement that uses the foot, pound, and second as base units, IEEE Std 260.1™-2004, IEEE Standard Letter Symbols for Units of Measurement (SI Units, Customary Inch-Pound Units, and Certain Other Units), Learn how and when to remove this template message. In the FPS system, the base units are the foot, pound, and second, which represent the base dimensions of length, mass, and time, respectively. The basic unit of force is the newton (N) and the basic unit of mass is the kilogram (kg). The unit of measurement is defined as the standard used for the measurement of the physical quantity. foot, where the subscripts f and m refer to the force and mass units designated by the name pound. The SI unit of electrical energy. When we say, for example, that the dyne is the CGS unit of force, this determines its definition: it is the force which accelerates a mass of one gram at the rate of one centimeter per second per second. When one-pound force is applied on a body and that body covers a distance of one foot in the direction of force, then one foot pound of work is said to be done. 1 / 3. One pound (1 lb) is the force that produces an acceleration of 32.1740 feet per second squared (32.1740 ft/sec 2) when applied against a known standard mass.
