## Definition of units

Let's see how both units in this conversion are defined, in this case Foot Pounds and Joules:

### Foot-pound (ft-lb)

The foot-pound force (symbol: ft⋅lbf or ft⋅lb), sometimes erroneously referred to as feet per pound (symbol: ft/lb), is a unit of work or energy in the Engineering and Gravitational Systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule.

### Joule (J)

The joule (symbol: J), is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889). One joule can also be defined as: The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one "coulomb-volt" (C⋅V), or as the work required to produce one watt of power for one second, or one "watt-second" (W⋅s) (compare kilowatt-hour – 3.6 megajoules).
