Shop Tools Reading a Metric Micrometer Each number on the sleeve of the micrometer represents 5.0 millimeters. Each of the ten equal spaces between each number, with index lines alternating above and below the horizontal line, represents 0.5 mm. The beveled edge of the thimble is divided into 50 equal divisions with every fifth line numbered: 0,5,10, . . . 45.
