    1. Rationale

    Micrometers are used for measuring material thickness. Through much testing and statistical analysis, the Micrometer Accuracy has been determined. The Accuracy has been determined for Electronic Digital Micrometers to be +/- 0.0003 inches and for Vernier Micrometers to be +/- 0.0004 inches.
