Detailed explanation-1: -The Vernier caliper is a device that employs an auxiliary (Vernier) scale which permits more accurate measurements of small fractions of a main scale division. The Vernier scale consists of N equally spaced divisions which have the same total length as (N-1) main scale divisions.

Detailed explanation-2: -It uses two graduated scales: a main scale similar to that on a ruler and an especially graduated auxiliary scale, the vernier, that slides parallel to the main scale and enables readings to be made to a fraction of a division on the main scale.

Detailed explanation-3: -We know the core use of Vernier Calipers is for measuring the distance between two opposite sides of a surface. We can measure the internal and external dimensions and even the height of an object with accuracy. It can measure up to one-hundredth of a millimeter.

Detailed explanation-4: -A vernier may be used on circular or straight scales where a simple linear mechanism is adequate. Examples are calipers and micrometers to measure to fine tolerances, on sextants for navigation, on theodolites in surveying, and generally on scientific instruments.

Detailed explanation-5: -A vernier calliper is defined as a measuring device that is used for the measurement of linear dimensions. It is also used for the measurement of diameters of round objects with the help of the measuring jaws.
