The thickness of the ring must be entered using the same
measurement system you used for the inner diameter.
If you only know the wire gauge, you need to convert it to inches or mm.
Different suppliers use different gauge systems and so it is best
to get the exact measurements directly from your supplier.
This chart provides standard conversions for Blue Buddha rings
and can be used as a general conversion guide
(however it is not guaranteed for other suppliers.)
