The foot-pound force, or simply foot-pound (symbol: ft·lb_f or ft·lb) is unit of work or energy (a scalar) and also a unit of torque (a vector). In Physics, mechanical work is the amount of Energy transferred by a Force. In Physics and other Sciences energy (from the Greek grc ἐνέργεια - Energeia, "activity operation" from grc ἐνεργός In Physics, a scalar is a simple Physical quantity that is not changed by Coordinate system rotations or translations (in Newtonian mechanics or A torque (τ in Physics, also called a moment (of force is a pseudo- vector that measures the tendency of a force to rotate an object about

Unit of energy

One foot-pound is the amount of energy expended when a force of one pound acts through a distance of one foot along the direction of the force. This article deals with the unit of force For the unit of mass see Pound (mass. A foot (plural feet or foot; symbol or abbreviation ft or sometimes &prime – the prime symbol) is a non-SI unit

1 foot-pound is equivalent to:

• 1. 3558179483314004 joules (exactly)
• 13558179. The joule (written in lower case ˈdʒuːl or /ˈdʒaʊl/ (symbol J) is the SI unit of Energy measuring heat, Electricity 483314004 ergs (exactly)

Related units of power

The foot-pound force per minute (ft·lb_f/min), foot-pound force per second (ft·lb_f/s), and horsepower are units of power derived from the foot-pound force. The Foot-poundal is a non- SI unit of Energy or work. The foot-poundal is the amount of energy expended when a Force of one Poundal

• 1 watt ≈ 44. The watt (symbol W) is the SI derived unit of power, equal to one Joule of energy per Second. 25372896 ft·lb_f/min
• 1 horsepower (mechanical) = 33000 ft·lb_f/min = 550 ft·lb_f/s

Unit of torque

As a unit of torque, one foot-pound is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point. The term pound-foot is sometimes used to distinguish the unit of torque from the unit of energy. Pound-foot is used by engine manufacturers in specifying the torque output of an engine.

1 foot-pound is equivalent to:

• 1. 3558179483314004 newton meter (exactly)

Newton metre is the unit of moment ( Torque) in the SI system The poundal is a non- SI unit of Force. It is a part of the Foot-pound-second system of units a coherent subsystem of English units introduced The slug is an English unit of Mass. It is a mass that accelerates by 1 ft/s² when a force of one Pound-force (lbf is exerted on it Because Energy is defined via work, the SI unit for energy is the same as the unit of work &ndash the Joule (J named in honour of James Conversion of units refers to conversion factors between different Units of measurement for the same Quantity.
