Homonym: gauge (Measure)
A "gauge" is a tool or instrument used to measure the size, amount, or capacity of something. It can refer to various types of measurements, such as thickness, pressure, or volume. For example, a pressure gauge measures the pressure of gases or liquids, while a wire gauge indicates the diameter of electrical wires.
In addition to measuring, "gauge" can also refer to the standard measurement itself. For instance, in firearms, the term gauge describes the bore diameter of a shotgun. A lower gauge number indicates a larger bore size, affecting the type of ammunition used and the firearm's performance.
