The value of each main scale divisions is half a degree(30') . The number of vernier scale divisions is 30. 29 main scale divisions are divided into 30 vernier scale divisions (30 VSD = 29 MSD ) Therefore value of 1 VSD = 29/30 MSD. Least Count (L.C.) = 1MSD - 1VSD = 1MSD - 29/30 MSD = 1/30 MSD = 1/30 x 30' (L.C.) = 1' (1 minute)
Hi, heres how you calculate least count of a micrometer. Use the given formula: Least Count (L. C) = Pitch/no. of divisions on micrometer barrel(thimble) where, Pitch = distance travelled by thimble on linear scale in one rotation. Hi, heres how you calculate least count of a micrometer.

Generally least count of micrometer varies instrument to instrument.. But common micrometers which are used in institute level laboratories have least count of 0.0001mm

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.
Least count refers to the highest level of accuracy that can be achieved in measurement. The general formula is: LC = (Value of 1 Main Scale Division) / (Total number of Vernier scale divisions).
The least count of the vernier can be measured by using the formula stated below. Least count (L.C) = 1 M.S.D - 1 V.S.D Example; vernier scale is constructed by taking 49 main scale divisions dividing them into 50 divisions ie. 49mm divided into 50 parts therfore 1 vsd=49/50 mm=0.98mm 1 MSD=1mm substituting in formula L.C = 1 M.S.D - 1 V.S.D L.C=1-0.98=0.02mm
The least count of a vernier scale in a diffraction grating is typically determined by the formula for the number of lines per unit length on the grating. By dividing the distance between two adjacent lines on the scale by this number, you can calculate the least count of the vernier scale.
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.'
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.

The formula for calculating the least count of a vernier height gauge is: Main scale division / (Total number of divisions on the vernier scale - 1). This formula helps determine the smallest measurement that can be read from the gauge.

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.
