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
value of 1 MSD/ no.of VSD for a vernier.

Least count= Pitch^number of division in a circle
Least count=least count of the main scale^ no. of division in a circle
Least count of micrometer screw gauge is found by dividing the pitch of screw gauge by total number of lines on the circular scale.
It is defined as the ratio between the pitch of screw and the number of head scale divisions

there is a big different between the vernier caliper and micro meter caliper,the vernier caliper they can use the outside and inside measurement while the micro meter caliper it's just only use outside measurement..
the least count of screw gauge is 0.01mm OR 0.001cms..
Tools for measuring lengths are : Screw gauge, vernier calipers,drafter, ruler ,circular scale ,etc . These tools are used for measuring lengths according to their different least counts.
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.

*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

today i observed errors between puppy dial reading & height gauge dial reading. this was 10μ to 20μ when we go to .1 mm
What part use in manifaturing height gauge? Whet are the L.C? tks. manesh
Former i.e. Vernier Caliper
Very little, the screw gauge checks the pitch of threads while the vernier caliper is use to accurately measure distances.
The zero error in the vernier calipers and micrometer screw gauge when the O mark on the main scale is not in line with the pointer.
