Understanding Vernier Caliper Least Count
Asked by Deeni ML · 2 years ago
Can someone explain what is meant by the 'least count' of a vernier caliper and why it is important for measurements?
1 Answer
The 'least count' of a vernier caliper is the smallest measurement that can be accurately read using the instrument. It is calculated as the difference between one main scale division and one vernier scale division. Mathematically, it is given by:
Least Count (LC) = 1 MSD - 1 VSD
where MSD is the main scale division and VSD is the vernier scale division. The least count is important because it determines the precision of the measurement. A smaller least count means the instrument can measure smaller differences in length, leading to more precise readings.
