# 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.

A Vernier scale on caliper may have a least count of 0. Divide 1 cm into that much number of divisions; the value obtained is the least count of the main scale in cm. Least count of an instrument is one of the very important tools in order to get accurate readings of instruments like vernier caliper and screw gauge used in various experiments.

Count the number of divisions on the Vernier scale. By repeating the observations and taking the arithmetic mean of the result, the mean value would be very close to the true value of the measured quantity. Comments Created By If the zero of the Vernier scale is to the right of the zero of the main scale then the error is positive.

Since the zero error is positive, the zero correction will be negative. Parts and function of vernier calliper Vernier Calliper least count Vernier calliper least count formula in mm Vernier calliper zero error What is the vernier calliper?

The movable jaws are attached to the vernier and they slide along the main scale. The stopwatch is more precise at measuring time intervals than the sundial because it has more “counts” scale intervals in each hour of elapsed time. In metrologythe least count of a measuring instrument is the smallest change in the measured quantity that can be resolved on the instrument’s scale. A stopwatch leats to time a race might lewst down to a hundredth of a second, its least count.

## Least count

Use a magnifying glass if necessary. Number of divisions on Vernier scale: In most Vernier calipers, the Vernier scale has 10 divisions.

To get the least count of the main scale, count the number of divisions on the main scale in one cm of it. Since the least count of the Vernier caliper is 0. The lower jaws A and B are used to measure length. Vernier caliper least count formula is calculated by dividing smallest reading of main scale with total number of divisions gernier vernier scale.
