Q1. What is the Vernier caliper least count?

Ans.

The Vernier caliper least count is the smallest measurement that can be read on the caliper scale.

  • The least count of a Vernier caliper is determined by the number of divisions on the main scale and the Vernier scale.

  • It is calculated by dividing the smallest division on the main scale by the total number of divisions on the Vernier scale.

  • For example, if the smallest division on the main scale is 0.1 mm and the total number of divisions on the Vernier scale is 10, the least cou...read more
