About these units

Newton Meter (N·m)

Definition
A newton meter (N·m) is the SI unit of torque, a one-newton force applied one meter from the pivot.
History
It combines the SI units of force and distance.
Current use
It is the standard torque unit for engines, fasteners, and machinery.

Newton Centimeter (N·cm)

Definition
A newton centimeter (N·cm) is one hundredth of a newton meter, used for small torques.
History
It is a smaller metric subdivision of the newton meter.
Current use
It rates small torques in electronics, instruments, and small motors.

Kilonewton Meter (kN·m)

Definition
A kilonewton meter (kN·m) is 1,000 newton meters, used for large torques and bending moments.
History
It scales the newton meter for heavy engineering.
Current use
It expresses structural bending moments and heavy-machinery torque.

Pound-foot (lbf·ft)

Definition
A pound-foot (lbf·ft) is an imperial torque unit, a one-pound force applied one foot from the pivot, about 1.356 N·m.
History
It developed with imperial mechanical engineering.
Current use
It is the common torque unit for US car engines and fasteners.

Pound-inch (lbf·in)

Definition
A pound-inch (lbf·in) is one twelfth of a pound-foot, used for smaller imperial torques.
History
It is the small-scale counterpart of the pound-foot.
Current use
It specifies tightening torque for small bolts and assemblies in the US.

Kilogram-force Meter (kgf·m)

Definition
A kilogram-force meter (kgf·m) is a metric-gravitational torque unit of about 9.807 N·m.
History
It was common in older metric engineering before the newton meter.
Current use
It still appears in some automotive and machinery torque specifications.
