Measurement Using Vernier Caliper

This video tutorial explains how to measure the diameter of a metal object using calipers. It covers the identification and reading of the main and vernier scales on the calipers. The main scale shows a reading of 1.3 cm, and the vernier scale aligns at 5. The tutorial demonstrates the calculation of the final measurement by adding the main scale reading to the product of the vernier scale reading and 0.01, resulting in a measurement of 1.35 cm.
