	pound force
		The unit of force in the British gravitational system of units, approximately the force which a mass of 1 pound exerts on whatever it is resting on on the Earth; that is, the weight of a mass of 1 pound.
		The weight of a mass of 1 pound varies from place to place; it weighs less at the equator than at the poles, and is lighter at high altitudes than at sea level.
		The pound-force, however, is unvarying; it is defined as the weight (a force!) that a body with a mass of 1 pound would exert at a location where the acceleration due to gravity was exactly 32.

	NationMaster - Encyclopedia: Pound force per square inch
		Pressure (symbol: p) is the force per unit area acting on a surface in a direction perpendicular to that surface.
		At 1 lbf/in², a force of one pound-force is applied to an area of one square inch.
		In the United States, a kip is sometimes a unit of mass that equals 1,000 avoirdupois pounds (used to compute shipping charges), or more often a unit of force that equals 1,000 pounds force (used to measure engineering loads).

	PowerPedia:Force - PESWiki
		Force is a vector quantity defined as the rate of change of the momentum of the body that would be induced by that force acting alone.
		The SI unit of force is the newton, while the English unit of force is the pound-force.
		Conservative forces are equivalent to the gradient of a potential, and include gravity, electromagnetic force, and spring force.

	Pound-force
		The pound-force is a unit of force or weight (properly abbreviated "lbf").
		The pound-force is equal to a mass of one pound multiplied by the standard acceleration of gravity (which is defined as exactly 9.80665 m/s
		In SI units, a pound-force is equal to exactly 4.4482216152605 newtons.

		If a force of one dyne is needed to move one square centimeter of the liquid or gas relative to a second layer one centimeter away at a speed of one centimeter per second, then the viscosity is one poise.
		A pond is the gravitational force on a mass of one gram; thus it is equal to 980.665 dynes or 0.002 204 622 6 pounds of force.
		One pound mole of a chemical compound is the same number of pounds as the molecular weight of a molecule of that compound measured in atomic mass units.

	Pound (mass) - Wikipedia, the free encyclopedia
		The pound is the name of a number of units of mass, all in the range of 300 to 600 grams.
		In many countries that use the SI or metric system, the pound (or its translation, for example, the German Pfund, the French livre, the Dutch pond, the Spanish and Portuguese libras, or the Chinese jin) is used as an informal term for half of a kilogram, therefore for this case the pound is 500 grams.
		Pounds are also used for the force definitions of weight, as well as for other forces, in which the pound force is a unit of force equal to 4.448 newtons.

	Force
		Force is any action that tends to maintain or alter the position of a body or to distort it.
		Because force has both magnitude and direction, it is a vector quantity and can be represented graphically as a directed line segment; that is, a line with a length equal to the magnitude of the force, to some scale, inclined at the proper angle, with an arrowhead at one end to indicate direction.
		In the case of gravitational force, the total weight of a body may be assumed to be concentrated at its centre of gravity.

	Pound-force Information
		The pound-force is equal to a mass of one avoirdupois pound (which is currently defined as exactly 0.45359237 kilogram) multiplied by the standard acceleration due to gravity on Earth.
		(The pound-force is thus roughly the force exerted due to gravity by a mass of one pound at the surface of the Earth.)
		It was in 1901 when the CGPM first adopted a standard acceleration of gravity for the purpose of defining grams-force and kilograms-force, a value often borrowed to define pounds-force, though other values such as 32.16 ft/s² (9.80237 m/s²) have been used as well.

	Units of Force & Torque
		The SI units of force and torque are the newton (N) and the newton metre (N·m) respectively.
		Force is defined as the rate of change of momentum.
		The torque generated about an axis is defined as the product of the component of the force perpendicular to the axis and the perpendicular distance between the line of action of the force and the axis.
