The pound-force is equal to the gravitational force exerted on a mass of one avoirdupois pound on the surface of Earth. Since the 18th century, the unit has been used in low-precision measurements, for which small changes in Earth's gravity (which varies from equator to pole by up to half a percent) can safely be … See more The pound of force or pound-force (symbol: lbf, sometimes lbf, ) is a unit of force used in some systems of measurement, including English Engineering units and the Pound-force should … See more • Foot-pound (energy) • Ton-force • Kip (unit) • Mass in general relativity • Mass in special relativity See more In some contexts, the term "pound" is used almost exclusively to refer to the unit of force and not the unit of mass.

WebIn the context of the gravitational FPS system, the pound-force (lbf) is sometimes referred to as the pound (lb). Pound-force as force unit and pound-mass as mass unit [ edit] Another variant of the FPS system uses both the pound-mass and the pound-force, but neither the slug nor the poundal. Webg c is the Universal Gravitational Constant, 32.174 lb m-ft/lb f-sec 2; g is the Local Acceleration due to gravity, ft/sec 2. The local acceleration due to gravity varies from location to location but is approximately 32.174 ft/sec2. The ratio of g g c is approximately 1.0 lb f /lb m; ρ is the density of the fluid, lb m /ft 3 Webn Net thrust, lbf FAR Fuel to air ratio g Gravity constant, 32.17 ft lbm lbf s2 h Enthalpy, BTU lbm hs Static enthalpy, BTU lbm ht Total enthalpy, BTU lbm h2t Enthalpy to temperature table lookup I Inertia, slug ft2 Research Engineer, 3000 Aerospace Parkway, Brook Park OH, AIAA Member. emergency edf number
