A size of 20 mm refers to a measurement of 20 millimeters, which is equivalent to 2 centimeters or approximately 0.79 inches. This size is often used in contexts such as jewelry, watch components, or various mechanical and electronic parts. To visualize it, 20 mm is roughly the width of a large button or the diameter of a standard coin, like a quarter.
