What are the least counts of a vernier scale and a micrometer screw gauge?

Question

Accepted Answer

The least count for a Vernier caliper is the smallest measurement that can be read accurately.

The least count of a Vernier caliper is determined by the number of divisions on the main scale and the Vernier scale.
The formula to calculate the least count is: Least Count = Value of one main scale division / Number of divisions on the Vernier scale.
For example, if the value of one main scale division is 1 mm and the Vernier scale has 10 divisions, the least count would be 0.1 mm.
The least count for a micrometer screw gauge is determined by the pitch of the screw and the number of divisions on the circular scale.
The formula to calculate the least count for a micrometer screw gauge is: Least Count = Pitch of the screw / Number of divisions on the circular scale.
For example, if the pitch of the screw is 0.5 mm and the circular scale has 100 divisions, the least count would be 0.005 mm.
