The screw gauge is used to measure diameter of a wire or thickness of a sheet. It consists of a screw, a stud, and two scales 1 main scale and 2 circular scale, as shown in figure. It is equal to the distance between two consecutive divisions on the main scale. The linear distance moved by the screw when circular scale is rotated by one division is called least count LC. In case of negative zero error, the 0 th mark on the main scale is barely visible. The density of a solid ball is to be determined in an experiment.

The precision of length measurements may be increased by using a device that uses a sliding vernier scale. Two such instruments that are based on a vernier scale which you will use in the laboratory to measure lengths of objects are the vernier callipers and the micrometer screw gauge. These instruments have a main scale in millimetres and a sliding or rotating vernier scale. In figure 1 below, the vernier scale below is divided into 10 equal divisions and thus the least count of the instrument is 0. Both the main scale and the vernier scale readings are taken into account while making a measurement.
