Description

Vernier Calliper
Vernier calliper was invented by French scientist Pierre Vernier for precise linear measurements. It is used to measure the length, diameter, thickness, depth, etc. precisely. A Vernier Calliper has two scales – a Main scale and a Vernier scale, which slides along the main scale. The main scale and vernier scale are divided into small divisions of different magnitudes. The main scale is graduated in cm and mm. The sliding Vernier scale has jaws projecting at right angles to it and also the main scale and a metallic strip. The zero of main scale and Vernier scale coincide when the jaws are made to touch each other. The knob is used to slide the vernier scale on the main scale. Screw is used to fix the vernier scale at a desired position.

Least Count (L.C.) of Vernier Calliper
The least count of vernier callipers is also known as the vernier constant. It is defined as the difference between one main scale division and one vernier scale division. It is also given by
