0. Objective
It is to measure the dimensions of a solid object using fine measuring instruments like:
1. Vernier caliper,
2. Micrometer Screw Gauge and
3. Spherometer Screw.
1. Vernier caliper
1.1. Apparatus
1. Vernier caliper, and
2. Parallelepiped solid object.
1.2. Theory
A very ingenious device for obtaining accuracy of a greater order than that obtainable by eye-estimation was invented by (Pierre Vernier), and is known by his name.

The vernier is a convenient attachment for determining accurately a fraction of the finest division on the main scale of a measuring instrument. The simplest vernier scale has (10 divisions) that correspond in length to (9 divisions) on the main scale. Each vernier division is therefore shorter than
