The most common is the standard scale, which shows the size of the ring on the inside, expressed in millimeters. The ring size varies from 13 to 25 mm, whereby it increases at a distance of 0.2 or 0.5 mm.
Some countries use their own scales. For example, the diameter can be specified in customs. In some cases, the measurement of the interior of the ring is used.
In Canada and the USA, conventional units of measurement are accepted that begin from zero to sixteen and increase at a distance of 1/4. In Australia and Ireland, letter names are used - from A to Z. in China and Japan, a special number system was adopted, the sizes of which vary from 1 to 27. There are special tables that have been created to translate values from one scale to another
