To find the least count of a micrometer in the imperial system, first convert the micrometer value to inches. Then, divide 1 inch by the number of divisions on the micrometer scale. This will give you the least count of the micrometer in the imperial system.

Least count of micrometer caliper in millimeter?

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.


What is formula to calculate least count of micrometer?

The formula to calculate the least count of a micrometer is: Least count = Pitch of screw gauge / Number of divisions on circular scale


How can you determine the least count of spherometer?

To determine the least count of a spherometer, you measure the total number of divisions on the circular scale and divide it by the total travel range of the micrometer screw. The least count is the smallest incremental distance that can be measured accurately by the spherometer.


How can find sensibility of vernier caliper and micrometer?

To find the sensitivity of a vernier caliper, measure the least count of the caliper (typically 0.02 mm) by dividing the smallest division on the main scale by the number of divisions on the vernier scale. For a micrometer, measure the least count (typically 0.01 mm) by dividing the smallest division on the main scale by the number of divisions on the thimble scale. Sensitivity indicates the smallest change in measurement that can be detected by the instrument.


What is meant by LC of a micrometer screw gauge?

In short least count is the least possible measurement that could be done using that device. In screw type least count is got by the formula pitch/number of head scale divisions And pitch is nothing but the distance moved as we give one complete rotation. So if 1mm is moved for one rotation the pitch is 1mm. If we have 100 equal divisions marked on the head scale then least count would come as 1/100 = 0.01 mm So we can measure the diameter of spherical bulrush so accurate as 3.24 mm or 2.53 mm Correct to two decimal places. We cannot get the accuracy as 3.534 etc.
