Objects measuring approximately 106 millimeter include a compact spice jar (approx. 105mm tall), a small tactical penlight (approx. 106mm long), and an industrial 4-inch (101.6mm) diameter cooling fan frame (often 105mm x 105mm).

Converting millimeter to inch is useful for international collaboration in engineering and manufacturing, interpreting product specifications from different regions, and ensuring compatibility between metric and imperial components in hybrid systems. It bridges the gap between metric-dominant and imperial-dominant markets.

A simple memory aid is to remember that 1 millimeter is roughly 1/25th of an inch (0.04 inch). For 106mm, you can quickly estimate 106 x 0.04 = 4.24 inches. For a visual reference, think of a standard 4-inch object and add a small fraction to its length.
