LONG EXPLANATION
Lower Jaws:
The upper jaws are the most prominent feature of a vernier caliper. These jaws are designed to grip objects firmly between them for measurement. One of the jaws is fixed and attached to the main scale of the caliper while the other one is attached to the vernier scale and is movable. The lower jaws allow the vernier caliper to measure outer dimensions of objects such as the length, width or diameter.
Upper Jaws:
The upper jaws are smaller in size and are attached to the upper portion of the vernier caliper. Similar to the lower jaws, one of these jaws is fixed and the other is movable. The difference between them and the lower jaws is that the upper jaws are used for measuring inside dimensions of hollow objects such as inside diameters of pipes, lengths and widths of boxes etc. The jaws are placed inside the place to be measured and then opened till they touch the edges and the reading is taken at that point.
