What is least count of vernier caliper?

Answer 1

Least count of vernier caliper= 1 MSD - 1 VSD.

Main scale usually would have 1 mm as the minimum division. Such 9 divisions, ie 9 mm would be divided into ten equal parts in the vernier. So VSD = 0.9 mm

Hence the least count = 1 - 0.9 = 0.1 mm

If the same is to be given in centimetre, then it will be 0.01 cm.

Answer 2

Hai,

I want to share my knowledge on this,least count is that difference between the main scale div and the vernier scale division.

It indicates that the degree of accuracy of measurement that can be achieved by that instrument,

Regards/RJ.MahesH

it can also be found by ..........

value(length) of 1 main scale div. / no. of div. on the vernier scale

for example a vernier calipers main scale div is .5mm and in vernier scale 25 div

so least count of vernier is .5/25 =.02mm

Answer 3

Least Count (LC) for an instrument is the minimum measurement that can be made accurately by measuring device. A measuring instrument cannot measure anything whose dimensions are less than the magnitude of least count. The instrument will have more precise measurement if the magnitude of least count is smaller value.

Answer 4

For calipers calibrated in inches it's 0.001" (a "thou").

Not sure about metric verniers - I think it's typically 0.05mm.

Note (as it often catches people out). A caliper is a vernier caliper only if it has a vernier scale, i.e. a secondary scale so calibrated that is has a magnifying effect. A caliper fitted with a digital read-out is not a "vernier caliper".

Answer 5

least count on vernier caliper is ..020 i.e 20 microns

Answer 6

The least count in vernier caliper is calculated by dividing the value of 1 msd[main scale division] by number of divisions in vernier scale.

Answer 7

0.05 is the least count of vernier calliper in matric system.

Answer 8

least count of vernier calliper 0.02

Answer 9

0.001 mm

Answer 10

0.02
