Micro meter

A micrometer is a precision measuring tool. They are used in manufacturing, machine shops, automotive work and the construction industry. “Mic” is shorthand for micrometer. Mics are very accurate measuring devices. Micrometers are used to take measurements with an accuracy of ~.0001″ or better in inches. Measurements in millimeters can be made down to .01mm or .001mm. The dial test indicator has the most accuracy and least measuring range. Micrometers are in the middle for both accuracy and measuring range. While still very accurate, one downfall of the micrometer is that they usually come with a 1″ measuring range (3-4″, 4-5″, etc.). Because of this they are often sold in sets to cover a larger measuring range. A 0-6″ micrometer set will cover the needs of most applications while a 0-12″ set is more than most people, especially hobbyists will need. 0-3″ sets are also common. Use a gentle, consistent amount of force when spinning the thimble. Using the ratchet on your micrometer can make this easier. Try spinning the thimble until you get three clicks on your ratchet. This will help you get repeatable measurements. You want to be consistent in your measuring so you know your readings are good. This is why taking multiple measurements is so important. When possible, measure the part multiple times to be confident your readings are accurate. A little practice on a As the spindle closes on the part being measured, it can be beneficial to slightly rock the micrometer in an eff...
