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.

• For example, if the main scale has divisions of 1 mm and the vernier scale has 10 divisions that cover 9 main scale divisions, the least count would be 0.1 mm.

The micro metro least count refers to the smallest measurement that can be accurately read on the micrometer scale.

• The least count of a micrometer is typically 0.01mm or 0.001mm, depending on the precision of the instrument.
