Question
Up to how many decimal places can a common vernier callipers measure the length in cm?
Solution
A common vernier calliper can measure the length accurately up to two places of decimal when the length is measured in centimetre
i.e. up to 1/100 the part of a centimetre.

How are they determined?
In the vernier callipers, there are 10 divisions on the vernier scale and 1 cm on the main scale is divided into 10 parts. While measuring the length, the zero of the vernier lies just ahead of the 1.8 cm mark and the 4th division of vernier coincides with a main scale division.
