What unit is not commonly used to measure torque?

The measurement of torque refers to the rotational force applied to an object and is commonly quantified using specific units that provide a clear indication of this force in relation to a distance from the pivot point. Inch-pounds, foot-pounds, and Newton-meters are all recognized units of torque; they incorporate both force and distance, indicating how much turning force is applied at a given radius.

Inch-pounds and foot-pounds express torque in terms of inches and feet, respectively, while Newton-meters derives its measurement from the metric system, utilizing Newtons as the unit of force and meters as the distance from the pivot point. These units are standard in engineering and mechanical settings where precise torque specifications are critical for safe and effective assembly or maintenance.

Centimeters, while useful in various contexts, do not serve as a standard unit of torque. Torque is not commonly expressed solely in centimeters, as it lacks the necessary component of force that produces a torque measurement. Therefore, centering this unit around distance without the associated force component makes it unsuitable for measuring torque. This inconsistency is why it stands apart as not being a common unit for torque measurement.
