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.
It is the minimum distance that vernier can measure.
the least count of a vernier calliper is 0.01
Multiply the divisions of the two scales together
0.01 mm
.01
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.'
.02mm
micro meter least count in British system
0.01mm
0.02
i think 0.01
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
*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
Standard is 0.01 mm
Least count = 1 Main scale division - 1 vernier scale division Why? The story is very interesting. That has been already explianed by me while answering such a question. Please....
1)Main Scale is fixed(It does not move) Vernier scale slides along main scale.2)Least count of Mainscale is 0.1cmLeast count of vernier scale is 0.01cm
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.
