Question

how do you determine the least count of a screw gauge​

Answer 1

Explanation:

A screw gauge of 100 divisions will move the cap scale along the main scale by 1/100 of mm-0.01 mm. This is the minimum value up to which a screw gauge can measure and is known as its least count. Or it is defined as the ratio between the pitch of the screw and the number of division on the circular scale.
