Torqueexact by definition
The foot pound-force is one pound-force applied at one foot from the axis, exactly 1.3558179483314 N·m. The value is exact because the pound-force and the foot are both exactly defined. It is the unit on North American torque wrenches and engine specifications.
Watch out: Written order distinguishes the conventions in careful usage: lb·ft for torque, ft·lb for energy. The distinction is widely ignored, and since the two have identical units the only reliable guide is context. A torque wrench setting is always a torque.
