The vernier caliper is used to measure what?

• A. Measures length to the nearest inch
• B. Inside and outside dimensions and depth
• C. Only internal diameters
• D. Only depth

Answer: (B)

The vernier caliper is designed to give precise measurements of three kinds of dimensions: external size, internal size, and depth. The large outside jaws grab the external dimensions, like the width or diameter of a object. The smaller inside jaws fit into openings to measure internal dimensions, such as the bore of a hole. The depth rod at the end measures how deep a recess or hole is. Because of these features, it can measure inside and outside dimensions and depth, not just one type of measurement.
