Explain how to measure length using vernier caliper

Explain how to measure length using vernier calipers.

Answers

Mutiso
Vernier calipers is used when higher accuracy in measurement is required and this cannot be done
using a metre rule.
Vernier calipers has two scales; main scale and vernier scale. Outside jaws are used to
measure both lengths and external diameters, inside jaws for measuring internal diameters while
the tail is used for measuring depths of cavities. The main scale is divided into cm and mm. The
vernier scale is divided into 10 equal divisions of 0.9 mm each. The accuracy of vernier callipers
is 0.10 mm.

The reading is taken in two steps;
a) The main scale is read at zero mark of the vernier scale. The values given in cm.
b) The vernier is read at the position where a mark on the vernier scale is exactly lined up
with a mark on the main scale. The values are given as a two decimal of a cm.
