How is the least count of Vernier caliper calculated?

Least count of a Vernier scale is calculated using the following formula, Least count = Smallest reading on main scaleNumber of divisions on Vernier scale=1mm10 = This is the least count for Vernier Callipers. Hence, the least count for Vernier Callipers is 0.1mm.

What is formula of Vernier caliper?

The formula for least count of a vernier caliper is given by the formula. Least count of vernier caliper = Smallest reading on the main scale/ Number of divisions on the vernier scale. = 1mm/10 divisions = 0.1mm. The length of the object is determined by using the formula. Length = MSR + (VSR x L.C)

What is the least count of vernier caliper?

A Vernier calliper scale can have a minimum count of 0.01 mm, while a micrometre can have a minimum count of 0.001 mm. The Least Count measuring instrument is determined mathematically by calculating the main scale reading by the cumulative number of divisions on the main scale. And if the method has a Secondary Size, too.

How do you find the additional digits on the vernier scale?

Read the Vernier scale. Find the first mark on the Vernier scale that lines up perfectly with any line on the main scale. That mark tells you the value of the additional digits. For example, the 14 on the Vernier scale aligns with a line on the main scale.

How much does a vernier measuring tool cost?

When does the jaws of the vernier caliper come in contact?

When the jaws of the vernier caliper come into contact, the zero of the main scale should coincide with the zero of the secondary scale. If both do not coincide then it is called zero error.
