What feature distinguishes an inside micrometer from an outside micrometer?

• A. It measures external dimensions
• B. It measures internal diameters
• C. It is designed for depth measurements
• D. It has a different scale

Answer: (B)

An inside micrometer is specifically designed to measure internal dimensions, such as the inner diameter of a hole or the spacing between two internal surfaces of a workpiece. This tool typically features expandable legs or a rod that can fit inside a cavity and make precise measurements of internal features, making it ideal for tasks where external measurements are not achievable. In contrast, an outside micrometer measures external dimensions, utilizing a different design to gauge the thickness or diameter of objects. Depth micrometers are tailored for measuring depths, while the scale system remains consistent across different types of micrometers, primarily differentiating them by their intended measurements. Thus, the accurate classification of an inside micrometer's functionality as it pertains to internal measurements is what solidifies option B as the correct choice.
