For non-dimensional gauges, see List of measuring instruments.
In science and engineering, a dimensional gauge or simply gauge is a device used to make measurements or to display certain dimensional information. A wide variety of tools exist which serve such functions, ranging from simple pieces of material against which sizes can be measured to complex pieces of machinery. Dimensional properties include thickness, gap in space, diameter of materials.[1][2]
