Converting millimeter to inch is useful for international collaboration in engineering, integrating components from different manufacturing regions, and adapting designs for markets that primarily use imperial measurements. It bridges the gap between metric-dominant scientific and industrial standards and imperial-based consumer or legacy systems.

A simple memory aid is to remember that 1 millimeter is roughly 0.04 inches. For 171 millimeter, you can quickly estimate by multiplying 171 by 0.04. For precision, always use the full conversion factor. Visualizing objects like a compact travel umbrella (folded) or a high-end fountain pen can also serve as a helpful reference.
