Want this question answered?
the screw gauge is an instrument which is used to measure length of an object.... the least count of an screw gauge can be found as follow.... l.c= pitch of the screw gauge no of divisions on main scale
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 general in any screw type instrument such as spherometer or screw gauge or micrometer the least count = pitch / no of head scale divisions Spherometer has an advantage of finding the depth in case of curved surfaces.
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
Because it can measure gauge of wire and has screw type structure.
the least count of screw gauge is 0.01mm OR 0.001cms..
0.02

The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm

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.

The importance of least count is that it has a capable of taking more accurate and precise measurements
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=0.02mmvalue of 1 MSD/ no.of VSD for a vernier.0.06513651237517
*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
LC FOR VERNIER CALIPER-0.1mm LC FOR MICROMETER -0.01 mm L.C- NO OF SMALLEST DIVISION ON MAIN SCALE ------------------------------------------------------- TOTAL NO OF DIVISION ON VERNIER SCALE
