Question

Define least count of a vernier callipers. How do you determine it?

February 4, 2024

Answer

The least count of vernier callipers is equal to the difference between the values of one main scale division and one vernier scale division.

It is calculated as below —

$Least count (L.C.)$ $= Value of 1 main scale div - Value of 1 vernier scale div$
