The importance of least count is that it has a capable of taking more accurate and precise measurements
The importance of least count ( the highest degree of accuracy of measurement) helps calculate the margin of errors when doing measurements.
least count of scale is 1mm
least count means L.C.
5 mm is the least count of theodolite.
The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm
least count for micrometer is 0.01mm0.01 mm
digital micrometer least count calculation
The formula to calculate the least count of a micrometer is: Least count = Pitch of screw gauge / Number of divisions on circular scale
The least count and maximum count of 6 electric appliances is 0.01MM and 25.00 MM respectively.
for a levelling staff the least count is 0.01in and in m 0.005m
Generally least count of micrometer varies instrument to instrument.. But common micrometers which are used in institute level laboratories have least count of 0.0001mm
The least count of a thermometer is the smallest temperature difference that it can measure accurately. Typically, for a standard mercury-in-glass thermometer, the least count is 0.1°C.
