A micrometer caliper is a measuring device for finding very exact measurements of an item. The least count of a micrometer caliper in millimeter is 0.02.
In case for micrometer, principle of pitch is used. Least count could be even micro meter But in vernier caliper, difference of main scale division and vernier scale division is the principle Least count could be 0.02 mm
In general in any screw type instrument such as spherometer or screw gauge or micrometer the least count = pitch / no of head scale divisions Spherometer has an advantage of finding the depth in case of curved surfaces.
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.
This micrometer has zero error.The zero marking on the thimble is below the datum line. So this micrometerhas a positive zero error.In this case we will take the reading on the thimble.Thimble reading = 0.03 mmSo the micrometer has a zero error of +0.03 mm.Whatever reading we take on this micrometer we would have to subtract +0.03 mmThe zero marking on the thimble is above the datum line. So this micrometerhas a negative zero error.In this case we will have to count the number of divisions on the thimble between the zero marking and the datum line.No. of divisions = 3Measurement of each division = 0.01mmSo the micrometer has a zero error of -0.03 mm.Whatever reading we take on this micrometer we would have to subtract -0.03 mm
micro meter least count in British system
least count for micrometer is 0.01mm0.01 mm
digital micrometer least count calculation
least count of a micrometer= pitch/no of division on the circular scale
The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm

Hi, heres how you calculate least count of a micrometer. Use the given formula: Least Count (L. C) = Pitch/no. of divisions on micrometer barrel(thimble) where, Pitch = distance travelled by thimble on linear scale in one rotation. Hi, heres how you calculate least count of a micrometer.
