Reading a micrometer takes practice.

If you think of the lines on the Sleeve as dollars and quarters,

the lines on the **Thimble** represent "pennies" or cents.

As the thimble rotates, you add those pennies to the dollars and quarters

O.K. so now we know how to read a micrometer! We just need some practice. In the picture below, the Sleeve shows 3 dollars and one quarter (25 cents). The Thimble shows one penny. To calculate this reading we add 3 dollars plus 1 quarter plus 1 penny. The actual measurement is .326 inches.

See if you can calculate the measurement below

Reading a micrometer gets easier with practice.

Here are some practice pages.
