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....
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).
1/30*.5
Least count of voltmeter is the value of one division on the scale. Formula is: Least count = Range/No. of divisions For example, if a voltmeter can measure from 0 to 40 V, and it has 100 divisions in total on the scale, then its least count is 40/100 = 0.4V
It could be a torque wrench.
least count of scale is 1mm
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
M1 = M2 x L1 / L2M1 is the torque setting of the wrench.M2 is the actual torque applied to the nutL1 is the normal length of the wrenchL2 is the extended length of the wrench (Length of wrench + length of adapter)Remember... Torque = Force x Radius
least count of a micrometer= pitch/no of division on the circular scale

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
the least count of screw gauge is 0.01mm OR 0.001cms..
