LEAST COUNT OF VERNIER CALLIPER PDF

The least count of an instrument is the smallest measurement that can be taken accurately Vernier callipers, an instrument for making very accurate linear. Vernier caliper least count formula is calculated by dividing smallest reading of main scale with total number of divisions of vernier scale. Least Count plays an important role in measurement devices like Vernier Caliper. This blog explains the procedure of calculating the least count of the metric.
