Convert N·m, kgf·m, lbf·ft and other units of torque, for example for tightening bolts.
Units of torque
The SI unit of torque is the newton meter (N·m). When tightening bolts, kgf·m and the imperial lbf·ft are common. Relationships: 1 kgf·m = 9.80665 N·m, 1 lbf·ft is about 1.3558 N·m and 1 lbf·in is about 0.1130 N·m. Always set tightening torque to the manufacturer’s specification.
