A micrometer ( my-KROM-it-ər), sometimes known as a micrometer screw gauge (MSG), is a device incorporating a calibrated screw for accurate measurement of the size of components. It is widely used in mechanical engineering, machining, metrology and most mechanical trades, along with other dimensional instruments such as dial, vernier, and digital calipers.
