The Vernier caliper least counts formula is calculated by dividing the smallest reading of the main scale with the total number of divisions of the vernier scale.LC of vernier caliper is the difference between one smallest reading of the main scale and one smallest reading of vernier scale which is 0.1 mm 0r 0.01 cm.

What is LC of vernier caliper?

The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm. The Least Count measuring instrument is determined mathematically by calculating the main scale reading by the cumulative number of divisions on the main scale.

What do u mean by least count?

In the science of measurement, the least count of a measuring instrument is the smallest and accurate value in the measured quantity that can be resolved on the instrument’s scale. The least count of an instrument is inversely proportional to the precision of the instrument.
