Subsection 2.5.3 Torque Units
Since torques are the product of a force with a distance, they have units of [force] \(\times\) [distance].
In the US standard system, torque is typically measured in foot-pounds (ft-lb) or inch-pounds (in-lbs.). These units represent the amount of force applied at a specified distance from the rotational axis. For example, one foot-pound of torque is equal to a force of one pound applied at a distance of one foot from the axis of rotation.
In the metric system, torque is measured in newton-meters (N-m) or in some cases, newton-centimeters (N-cm). The newton-meter represents the force (in newtons) applied at a distance of one meter from the rotational axis. Similarly, the newton-centimeter is the force (in newtons) applied at a distance of one centimeter from the axis of rotation.
