A 30mm circle has a diameter of 30 millimeters, which is roughly equivalent to 1.18 inches. Visually, it appears as a small coin or a button, slightly larger than a quarter. The circle is perfectly round, with all points on the edge equidistant from the center. It's commonly used in various applications, such as in design, crafts, and engineering.
