How do you calculate least count of micrometer?

Answer 1

least count is the lowest value that can be measured by an instrument,For a micrometer the screw moves or advances 1mm for 2 complete revolutions of thimble.Which is divided into 50 divisions

so it takes 100 divisions (50*2) for 1 mm

therefore 1/100=0.01mm

this is the least count of a micrometer(screw gauge)

Answer 2

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.

Answer 3

The least count of micrometer is 0.01mm and it is very important in the physics labs and sometimes also in Biology labs. The observations with these instruments should be very carefully and precisely carried out because chances of human error are high.

it is calculated as:

least count = pitch of screw/ no. of divisions on circular scale

Answer 4

Least count fo micrometer is 0.001mm=1 micron.

Answer 5

Type your answer here... THE SMALEAST MEASUREMENT THA CAN BE MEASURED WITH AN INSTRUMET IS CALLED LEAST COUNT OF MICROMETER

Answer 6

for screw gauge accuracy is up to 0.01mm.

Answer 7

0.001mm
