Micrometer works on the principle of screw gauge.

• Micrometer measures small distances with high accuracy.

• It consists of a calibrated screw and a thimble with a scale.

• The screw moves the spindle to measure the distance.

• The scale on the thimble gives the reading.

• The principle of screw gauge is based on the pitch of the screw and the number of divisions on the thimble.

• The accuracy of the micrometer depends on the pitch of the screw and the number of divisions on the thimble.

The least count of a micrometer is the smallest measurement that can be read on the scale.

• The least count of a micrometer is determined by the number of divisions on the thimble and the pitch of the screw.

• For example, if the thimble has 50 divisions and the pitch of the screw is 0.5 mm, the least count would be 0.01 mm.

• The least count is important for accurate measurements and should be taken into consideration when using a micrometer.
