Using a Vernier caliper, the thickness of an M & M is 4.9 mm or 0.49 cm.
<h3>What is Vernier caliper?</h3>
A Vernier caliper is an instrument used to measure the internal and external diameter of small objects such as the the diameter of a rod, the internal diameter of a tube, or the thickness of a plate.
The Vernier caliper measures to an accuracy of 0.1 mm or 0.01 cm
Vernier calipers have two scales;
- the main scale
- the Vernier scale
When taking measurements from a Vernier caliper, the readings in the main scale and the Vernier scale are summed together.
For example, in the measurement of the thickness of an M & M;
the main scale reading = 4 mm
the Vernier scale reading = 0.9
total measurement = 4 mm + 0.9 = 4.9 mm
In conclusion, Vernier calipers are used to measure the diameter of small objects in units of mm.
