What are micrometers?

The micrometer is used to measure linear outside and inside dimensions.Both outside and inside micrometers are calibrated and read in the same manner. Measurements on both are taken with the measuring points in contact with the surfaces being measured.
There are the frame, anvil, spindle, locknut, sleeve, sleeve numbers, sleeve lone line, thimble marks, thimble, and ratchet on a micrometer. Micrometers are calibrated in either inch or metric graduations and are available in a range of sizes.
Usually, most micrometers are designed to measure objects with accuracy to 0.001 (one-thousandth) inch. Additionally, micrometers can also measure in 0.0001 (one-thousandth) inch. Micrometers are also available to measure in 0.0001 (ten-thousandths) of an inch. This type of micrometer should be used when the specifications call for this much accuracy.
