Wire and Ring Inner Diameter Reference
Table
The Table below compares the 2 most
popular wire gauge systems, decimal inches, fractions and metric
for your convenience.
For more information on rings etc please go to
Store Info and Help and look under Project and Product Selection
Help
Note that their are 2 gauge systems; SWG
and AWG. 14AWG is almost the same as 16SWG. For the larger wire
we use SWG.
To prevent confusion it may be best to refer
to decimal inches. Also please note that all rings have a certain
amount of spring back. All rings will be slightly larger than
the listed inner diameter. The harder the material the larger
the spring back.

* People familiar with gauges will notice
we use AWG for smaller wire and SWG for larger wire. We know it
is confusing; unfortunately it was a convention we adopted years
before we knew there was a problem. Please use decimal inches
when confused.
For the more gauge savvy customers you
can refer to the following tables.
