How to measure the length by vernier caliper

Vernier Calipers are a precision measuring instrument commonly used to measure length, depth, and internal or external dimensions with high accuracy. The tool consists of a main scale engraved on a fixed jaw and a sliding Vernier scale attached to a movable jaw. The jaws measure external dimensions, while a pointed tail is used for internal or depth measurements.

To use the instrument, place the object between the jaws, adjust the sliding jaw to fit snugly, and read the measurement by aligning the main scale and Vernier scale marks. The smallest division on the Vernier scale represents the instrument's least count, indicating the precision level.

Vernier Calipers are indispensable in fields like engineering, machining, and scientific research, where precise measurements are critical."
