N.m. stands for Newton-Meter, which is a unit of measurement for torque. However, there are several other synonyms that can be used in place of N.m. when discussing torque measurements. One such synonym is pound-feet (lb-ft), which is commonly used in the United States. Other possible alternatives include kilogram-meter (kg-m), and foot-pound (ft-lb), which are more commonly used in Europe and the United Kingdom, respectively. Regardless of the unit of measurement used, torque is the rotational force applied to an object, and it plays an essential role in many mechanical and engineering applications.
