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

• The least count is determined by the number of divisions on the micrometer scale and the resolution of the digital display.

• For example, if the micrometer scale has 50 divisions and the digital display has a resolution of 0.001mm, the least count would be 0.02mm.

• To calculate the least count, divide the smallest division on the micrometer scale by the number o...read more
