Vernier Calipers

A caliper (also calliper, or a pair of calipers) is a device used to measure the distance between two opposite sides of an object e.g. diameter of a round object. A caliper can be as simple as a compass with inward or outward-facing points. The tips of the caliper are adjusted to fit across the points to be measured, the caliper is then removed and the distance read by measuring between the tips with a measuring tool, such as a ruler.
It is used in many fields such as mechanical engineering, metalworking, forestry, woodworking, science and medicine.
I have find this video very effective for learner who is new to use a vernier calipers.

  Another video that I find very focused and detailed is also here. Advanced learners that have studied it previously would find it very helpful in revising the features and working of a vernier calipers.
