About the foot-pounds unit

1 foot-pound (ft·lb) of torque is the turning moment produced by one pound-force acting perpendicular to a one-foot lever arm: 1.3558179483314004 N·m. Note that the same words "foot-pound" also name an energy unit (1 ft·lb = 1.3558 J), torque and energy are physically different quantities that only happen to share the force × distance combination. In workshops this torque unit is written ft-lb, ftlb, ft/lb, lbf·ft or lb-ft; all of these mean exactly the same value.
