A torque wrench is used to measure the rotational force required to tighten a threaded fastener, such as the lug nuts on a car. The data and settings of a torque wrench are often displayed in foot-pounds or Newton meters. We often come across the question of what the parameters are involved in measuring torque. Below, we have the answer.

Length and force are the parameters involved in measuring torque. When it comes to determining quantifiable results with most measurement devices, two or more parameters are required. For instance, the volume of a pyramid is dependent on one-third the measurement of the base multiplied by the height. Or, pressure is a function of weight and area.

The idea that measurements are dependent on two or more parameters becomes clear when considering the philosophy of Pragmatism which claims that reality only exists in relationship. Nothing can exist absolutely independent, even measurements. Essentially, that’s what calibration is: assessing the relationship between measurements of test equipment in a manner that establishes the mutual dependency of all measurements on each other.
