In order to read a micrometer, you will use the numbers on the thimble and on the sleeve. The numbers on the sleeve are broken down into 4 parts. Think of them as dollars with whole numbers and quarters. The numbers on the thimble can be represented as pennies, or ones. If the sleeve is at 9 3/4 and the thimble is at 4, the reading would be .979.

The digital micrometer just like the analog micrometer is used to measure thicknesses, diameters, etc. The main difference is that it is easier for the user to read (as is true of most digital vs. analog things).

A micrometer is equal to exactly 1 micrometer.
A digital micrometer is the easiest to read as it displays the exact reading on a screen.

An imperial micrometer can measure to within 0.001in (1000th of an inch).
Put it between two jaw piece micrometer. Screw close movable jaw. And read on a micrometer ruler.

The smallest measurement that can be read with a micrometer is typically 0.01 mm or 0.001 cm, depending on the type of micrometer being used. This would have two significant figures in the measurement.

.000345 that is just simple math right of the point the places start 10th 100th 1000th and so on read away okay, but, how did you determine the .00345? In other words, hwo do you read the caliber? How did you egt those numbers?
Micrometer is a measuring device. And the measurement accuracy is 0.01 mm. Object to be measured between the left jaw and screw it shut, and the size of the cache line read.
The smallest division on the main scale of a micrometer gauge typically corresponds to 0.5 mm or 0.025 inches. This is the precision at which the main scale can be read.
