To convert foot-pounds to joules, enter the value in the first field. The result in joules is calculated automatically using the exact conversion factor.
1 ft·lbf ≈ 1.35581794833 J
1 J ≈ 0.737562149277 ft·lbf
Formula: J ≈ ft·lbf × 1.35581794833
ft·lbf ≈ J × 0.737562149277
Definitions: 1 ft·lbf = 1.35581794833 J
The foot-pound (ft·lbf) is the work done by a force of one pound-force over a distance of one foot, about 1.356 joules. It is used in the United States for the muzzle energy of ammunition and for impact energy, and it should not be confused with the pound-foot, a unit of torque.
The joule (J) is the SI unit of energy and work: the energy of one newton acting over one meter, or of one watt working for one second. It is a small unit, roughly the energy needed to lift a small apple by one meter.
