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).
least count of a spectrometer is equal to 1' (one minute)
the least count of screw gauge is 0.01mm OR 0.001cms..

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
least count of scale is 1mm
least count means L.C.
5 mm is the least count of theodolite.

for a levelling staff the least count is 0.01in and in m 0.005m
least count for micrometer is 0.01mm0.01 mm
The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm
the least count of travelling microscope = 0.001 cm
digital micrometer least count calculation
The importance of least count ( the highest degree of accuracy of measurement) helps calculate the margin of errors when doing measurements.
