The least count of Vernier Calliper is

The least count of Vernier Calliper is 0.1 millimeter which means it can measure lengths with accuracy up to one tenth of a millimeter. Least count is defined as the smallest measurement that an instrument can read. Vernier Calipers are widely used in laboratories engineering workshops and industries for accurate measurement of internal and external diameters depth and thickness. This high level of precision makes the Vernier Calliper essential in fields where exact dimensions matter. Its design combines a main scale and a sliding Vernier scale which allows users to measure more accurately than a simple ruler.
