A vernier caliper (or vernier) is a common tool used in laboratories and industries to accurately determine the fraction part of the least count division. The vernier is a convenient tool to use when measuring the length of an object, the outer diameter (OD) of a round or cylindrical object, the inner diameter (ID) of a pipe, and the depth of a hole. The vernier caliper is used in length measurements to gain an additional digit of accuracy compared to a simple ruler.
A vernier caliper is a measuring tool. It can make inside, outside, or depth measurements .It is marked in both USCS and metric divisions called a vernier scale. A vernier scale consists of a stationary scale and a movable scale, in this case from the vernier scale.

A vernier scale has a movable scale that is parallel to fixed scale .These precision measuring instruments are capable of measuring outside and inside diameters and most will even measure depth. Vernier calipers are available in both imperial and metric scales. The main scale of the caliper is divided into inches, most measure up to 6 inches. Each is divided into 10 parts, each equal to 0.001 inch. The area between the 0.00i marks is divided into four. Each of these divisions is equal to 0.025 inches.
