The least count of a micrometer is 0.01.

• Least count refers to the smallest measurement that can be read on a measuring instrument.

• In this case, the micrometer can measure to the nearest 0.01 mm.

• This means that any measurement taken with the micrometer will have an uncertainty of +/- 0.005 mm.

• To get a more accurate measurement, a micrometer with a smaller least count can be used.
