In Italy we are used to express the nylon diameters in parts of centimeters and this may cause confusion to anglers from countries where centimeters are replaced by inches. Many anglers normally use “X” denominations (1X, 2X and so on) and when they ask for a new piece of nylon to replace the tippet, are unable to mention the proper diameter in centimeters. On the other side, when we must tell anglers what is the best tippet “size” for a certain environment, we have no idea of its “foreign” counterpart.

The following may help solve the problem…
