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.
The least count of a Vernier caliper is the smallest measurement that can be resolved using the instrument. It is typically 0.02 mm or 0.001 inches for most Vernier calipers used in industries and workshops. This means that the caliper can measure differences in dimensions as small as 0.02 mm or 0.001 inches.
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".
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.

What is the unit of vernier scale reading of vernier caliper?
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
How can find sensibility of vernier caliper and micrometer?
To find the sensitivity of a vernier caliper, measure the least count of the caliper (typically 0.02 mm) by dividing the smallest division on the main scale by the number of divisions on the vernier scale. For a micrometer, measure the least count (typically 0.01 mm) by dividing the smallest division on the main scale by the number of divisions on the thimble scale. Sensitivity indicates the smallest change in measurement that can be detected by the instrument.
What are all of the similarities between the Vernier caliper and screw gauge?
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.
How do you measure the least count of vernier?
The least count of a vernier scale is calculated by dividing the smallest division on the main scale by the total number of divisions on the vernier scale. This calculation gives the value of one vernier division.
How do you use vanier caliper?
To use a Vernier caliper, first close the jaws and check that the zero on the Vernier scale aligns with the main scale. Next, open the jaws and place the object you want to measure between them. Read the measurement where the lines on the Vernier scale align with the main scale.
Least count of vernier?
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.
What is the least count of the vernier caliper for digital?
0.01mm
What is the least count of a vernier carliper?
Least Count [L.C]:-Least count is minimuim acuurate value meauserd by instrument.Least Count of Vernier Callipers:-The minimum value measured is 0.1mm but nowa days [l.c] is of 0.5mm.'
What is the difference between Screw Gauge and 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

A vernier calliper has 20 divisions on the vernier scale one centimeter on main scale is divided into 20equal parts Find the least count of vernier parts?
The least count of the vernier caliper is calculated by dividing the smallest division on the main scale by the total number of divisions on the vernier scale. In this case, 1 cm on the main scale is divided into 20 equal parts, so the least count is 1 cm / 20 = 0.05 cm or 0.5 mm.
