The least count of a vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the main scale and the vernier scale.

• It is calculated by dividing the smallest division on the main scale by the number of divisions on the vernier scale.

• For example, if the smallest division on the main scale is 0.1 mm and the number of divisions on the vernier scal

O.001 is equal to 1 micron.

• O.001 is a unit of measurement for thickness or diameter.

• It is commonly used in industries such as manufacturing and engineering.

• For example, a sheet of paper may have a thickness of 0.1 mm or 100 microns.

• O.001 is equivalent to 1 micrometer or 1/1000th of a millimeter.

The least count of a micrometer is the smallest measurement that can be read on the instrument.

• The least count of a micrometer is usually 0.01 mm or 0.001 mm.

• It is determined by the number of divisions on the thimble and the pitch of the screw.

• For example, if the thimble has 50 divisions and the pitch of the screw is 0.5 mm, the least count would be 0.01 mm.

• The least count is important for accurate measurements and sho...read more
