Vernier caliper: Vernier caliper is a measuring tool that is used to determine the width, height, and radius of a body. In comparison to the usual scale, the Vernier scale on the main scale allows for more precise measurements.
The formula for least count of a vernier caliper : Least count of vernier caliper Smallest reading on the main scale/ Number of divisions on the vernier scale 1mm/10 divisions 0.1mm
The length of the object is determined by using the formula :
Where MSR is the main scale reading , VSR is the vernier scale reading, and L.C is the least count of the vernier caliper.
Hence the formula for the length measured by a vernier caliper is .
