Frequently Asked Questions About Vernier Calipers
Posted on September 15, 2015 by Stipe Markovics | 3 Comments
In this article our experts will try to address some common questions [Frequently Asked Questions (FAQs)] regarding the Vernier Caliper and its usage as well as clear up some conceptual problems faced by beginners.
Q.1: Why use a vernier caliper instead of a regular meter rule?
Ans: A vernier caliper offers a lot more accuracy than a regular meter rule. We can measure lengths up to a millimeter on a regular meter rule but a vernier caliper with 10 equal divisions on the vernier scale allows us to measure lengths as small as 0.1 mm accurately
Q.2: What is the principle behind the vernier caliper?
Ans: The principle behind the vernier scale lies in the difference between the divisions on the main scale and the vernier scale. This difference is very small and usually it is such that 9 divisions on the main scale are equal to 10 divisions on the vernier scale. This means that only one division on the vernier scale will coincide with the main scale division when a measurement is made and this coincident point is used to find the vernier scale reading.
Q.3: What is meant by the least count?
.Ans: The least count refers to the smallest measurable length by the vernier caliper. It can be found by dividing the difference of 1 Main scale division by the number of divisions between two vernier scale values (usually 10). i.e 1 Main Scale Division/10.
Q.4: What are the lower jaws of a vernier caliper used for?
Ans: The function of the lower jaws is to measure the outer diameter of an object such as a tube, sphere or cylinder.
Q.5: What are the upper

To determine i) The volume of the given cylinder by measuring its length and diameter
ii ) The volume of the given sphere by measuring its diameter.
Apparatus : Vernier Calipers,Cylinder and sphere.
Description of Vernier Calipers: A Vernier calipers consists of mainly two parts i) A 2cm wide 15cm long rectangular metal strip .The left end bottom side of this strip consists of a fixed jaw 1 (A) and at the same end jaw 2(C) at the top of this strip. On the strip a scale (5)is graduated in Inches along the upper edge and another scale(4) is graduated in Centimeters along the lower edge. This is called Main
