Vernier caliper least count in mm

Introduction The vernier caliper is a measuring device used to calculate the internal and external diameters of the given object along with the height and depth of the specimen in a linear dimension manner. Pierre Vernier, a French mathematician, innovated vernier calipers to calculate the accurate measurement of the object linearly. The word caliper is defined as the instrument having two jaws to precisely calculate the given objects’ diameters. The working principle behind the vernier caliper is that two scales of different sizes are taken into consideration, and the difference helps calculate the object’s accuracy. The advantage of the vernier caliper is that it can calculate the objects having a diameter up to 1mm. Parts of Vernier Caliper Vernier Caliper consists of 8 parts, and each of them is mentioned below. • Inside Jaws: It helps measure the internal dimension of the given objects. • Outside jaws: It helps calculate the external dimension of the given objects. • The Main Scale measures in millimeters (mm) or inches. • Vernier scale measures in millimeters (mm) or inches. • Measuring depth Probe: It helps calculate the depth of the given objects. • Retainer: The utilization of retainer is to block the moving part of the caliper. Preparation for using a vernier caliper To measure the height, depth, or diameter of the given object, the object needs to be put in between the outer and inner jaws of the vernier caliper. Out of the two, one is a fixed jaw, and the other...
