What type of measurement is NOT typically taken with an outside micrometer?

The measurement that is not typically taken with an outside micrometer is the internal dimensions of cylindrical parts.

Outside micrometers are primarily designed to measure the external dimensions of objects, such as thickness, outside diameters, and similar external measurements. The principal mechanism of an outside micrometer features two parallel measuring faces that come together to measure the outside dimension of a workpiece.

For internal dimensions, such as the inner diameter of cylindrical parts, a different type of tool called an internal micrometer or a caliper with an internal measurement capability is needed. These tools have specialized tips or mechanisms that allow them to accurately gauge the inside dimensions of a component.

Thus, the function of measuring internal dimensions falls outside the scope of what an outside micrometer is designed for.
