What is a foot-pound?
A foot-pound of torque is one pound-force applied one foot from the pivot, about 1.356 Nm. US fastener specifications and engine output figures use it. Some manuals write it lb-ft to distinguish torque from energy.
What is a newton meter?
The newton meter is the SI unit of torque: one newton of force applied at one meter from the pivot. It is the unit on almost every metric torque wrench and vehicle service manual.
