A micrometer (/maɪˈkrɒmᵻtər/ USdict:mī·krŏm′·ĭ·tər), sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for precise measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are usually, but not always, in the form of calipers (opposing ends joined by a frame), which is why micrometer caliper is another common name. The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil.
Micrometers are also used in telescopes or microscopes to measure the apparent diameter of celestial bodies or microscopic objects. The micrometer used with a telescope was invented about 1638 by William Gascoigne, an English astronomer.
The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria and is also commonly used in plastics manufacturing. Micrometres are the standard for grading wool (referring to the diameter of wool fibres). Any wool finer than 25µm can be used for garments, whilst coarser grades are used for outerwear, rugs, and carpets. A human hair ranges from 17 to 181 µm.
The symbol for the SI prefixmicro- is a Greek lowercase mu. In Unicode, it has the codepoint U+00B5 (µ), distinct from the codepoint U+03BC (μ) of the Greek letter lowercase mu, so that machines can recognize it as the SI prefix symbol rather than as a letter. Most fonts use the same glyph for the two characters.
Bob Welds explains how to read a metric micrometer.

THE THREE STEPS OF MEASURING WITH A MICROMETER:
Clean the micrometer: Use soft cloth to wipe down the anvil and the spindle of the micrometer. Removing any dust or debris present on the measuring faces will ensure precise measurement.
Begin to measure: Place the object you are measuring against the micrometer’s anvil. Tighten the device until the spindle is firmly pressed against the object. If you need to prevent your thimble from turning use the locking lever or wheel to secure it in place. You can also fasten the frame on a micrometer stand to free up both of your hands if so desired.
Read the measurement: Follow the four step measuring process, noted in detail below.
HOW DO YOU READ MICROMETERS?
FOLLOW THIS SIMPLE FOUR-STEP PROCESS TO READ MICROMETERS:
how to read a micrometer
STEP 1: Read the sleeve measurement
STEP 2: Next, read the thimble measurement
STEP 3: Now read the vernier
The vernier will provide the ten-thousandths place of your decimal measurement.
STEP 4: Finally, add it up!
Add step 2 to step 1 (add your thimble measurement to our sleeve measurement), and then just "tack" step 3 (your vernier measurement) onto the end. As an example, if you're measuring something that is 0.1234", you'd find the .100 on the sleeve (step 1), the .023 on the thimble (step 2), and then you'd add . 023 to .100 for a combined .123. Then, you'd find .0004 on the vernier scale and just tack that onto the end.
TECH TIP: Sometimes, for people who are learning this, when you have .123, and you see the .0004 on the vernier scale, it's easy to misunderstand, leave out a zero (.004), add it to .123 and get .127. It's easier to understand if you forget about the zeroes and just put the number from the vernier scale onto the fourth place (the ten-thousandths place), at the end of the .123, to obtain the correct measurement of .1234.
MICROMETER MAINTENANCE & TECH TIPS:
Maintenance & Cleaning: Before use, gently but thoroughly remove oil, dust and dirt from the entire surface of the micrometer, taking care not to damage the measuring faces. Clean the measuring faces with a clean cloth before and after taking any measurements.
Calibrate When Necessary: When a micrometer is at its minimum reading, the horizontal line on the sleeve should line up with the ‘0’ on the thimble. If that is not the case, calibrate the micrometer by rotating the sleeve. Each micrometer comes with an adjusting wrench for this specific purpose. Verify the horizontal line on the sleeve lines up with the ‘0’ on the thimble before each use.
Micrometer Storage: When not in use, properly store your micrometer in an environment free of heat, dust, humidity, oil, and mist. If you have electronic (digital) micrometers, remove the batteries if they'll be stored for a long period of time.
