When would you opt to use Newton-Meters in relation to torque?

Using Newton-Meters in relation to torque is appropriate in mechanical applications that require precise torque settings because Newton-Meters is a unit that directly relates to torque, which is the rotational force applied at a distance from a pivot point. Torque is crucial in various mechanical contexts, such as when securing bolts or adjusting components to ensure proper assembly and performance. The formula for torque involves multiplying the force applied by the distance from the pivot point, hence the relevance of the unit.

In contrast, measuring force solely would not require the use of Newton-Meters, as forces are typically measured in Newtons, not a combination of force and distance. Electrical applications often utilize different units relevant to voltage, current, or power, rather than torque. Additionally, measuring temperature pertains to entirely different physical properties and would use units like degrees Celsius or Fahrenheit, not Newton-Meters.
