Notes:

All ring sizes are in steps, 1/8 minimum, pure conversion is not possible. A nearest conversion is used here.

"<" represents a size smaller than the value shown, and is smaller than values available for this sizing system.

"~" represents an approximate next larger size for that measuring system.

"-" hyphenated values represent a variant between these two size values.

"--" alone represents that no suitable size conversion is available for selected size.
