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.
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

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.
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".
least count on vernier caliper is ..020 i.e 20 microns
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.
0.05 is the least count of vernier calliper in matric system.

The least count of vernier caliper is 0.01mm while the least count of screw gauge is 0.001 mm. ... Difference between screw gauge and vernier caliper in tabular form. Micrometer Screw Gauge Vernier caliper It has a circular scale. It has a vernier scale. It rotates to measure the objects. It slides to measure the length.
In case for micrometer, principle of pitch is used. Least count could be even micro meter But in vernier caliper, difference of main scale division and vernier scale division is the principle Least count could be 0.02 mm
No unit for vernier scale coincidence. But as we multiply it by least count which has unit then we get vernier scale reading with the same unit. Of course main scale reading and vernier scale reading would have the same unit
First we keep the body in between the jaws of the caliper. Then we note the main scale reading and then vernier coincidence. Vernier coincidence is to be multiplied by the least count of the device. This is added with the main scale. That will be the required value of the dimensions of the object.
To measure the inside diameter of a ring using a vernier caliper, you must use the small jaw or the internal jaw of a vernier caliper.
The least value which can be measured from any measuring instrument or device is called its least count. Generally the least count of a vernier caliper is 0.02mm.You can get a least count of 0.01mm in Digital vernier caliper.

*Micrometer have a rotary handle and whereas vernier have a slider. *Micrometer is for measuring diameters while vernier is for measuring inside & outside diameter as well as depth. *Least Count of Vernier Caliper is 0.02mm *Least Count of Micrometer is 0.01mm
