A caliper is used to measure which of the following with precision?

• A. Inside dimensions only
• B. Outside dimensions only
• C. Inside or outside dimensions and sometimes thickness with precision
• D. Volume

Answer: (C)

Calipers are precision tools for measuring linear dimensions. Their design includes two sets of jaws: the smaller inside jaws for measuring interior dimensions, and the larger outside jaws for measuring exterior dimensions. Many calipers also have a depth rod or probe that extends from the end to measure depths or thicknesses of features like slots or holes. The readings come from a vernier, dial, or digital scale, giving measurements to a small fraction of an inch or millimeter, depending on the instrument. Volume isn’t measured directly by a caliper; you’d need different methods or to derive volume from multiple measurements. So the tool’s capability to measure inside or outside dimensions and, in many cases, thickness or depth with precision is what it’s designed for.
