    How many mm is 2g?

    I've been looking at 2g jewelry online, and sometimes it is listed as 6mm and sometimes as 6.5mm. Will my ears even care? Is 2g "officially" one or the other? Thanks

    * nipples
    * navel

    It's both, same how sometimes 00g is either 9 or 10mm since the metric system is not always an exact conversion. Stretchy lobes will not care about the difference that much. My stupid conches however do, so I have to be careful to make sure my plugs are 6mm. I wish things were more standardized.

    6.5 for jewelry that is machined, ie SS, Ti

    hand made/imported jewelry can vary from 6-7mm
    go by millimeters and not gauges and it is much eaiser.

    Official American Wire Gauge tables list 2 gauge as .2576". This is per the table in Machinery's Handbook, the reference bible for machinists and mechanical designers. With much jewelry being made in metric countries or being hand made there are huge variations. I have seen supposed 2 gauge items as small as about .230".

    00 gauge is officially .3648", closest to 9mm (actual 9.26mm) and 000 gauge is .4096" or closest to 10mm (actual 10.4mm).

    Tattoos on about 60% of the body but none on hands or above the normal T shirt neckline.

    Agreed but Congress stopped full Metric conversion in the USA in the late 1970s IIRC. I suspect that they could not learn it! Most US industry that is concerned with exports has converted. The USA is the last country on Earth which has not converted to Metric so far as I know.

    You beat me!

    The U.S. won't be doing a hard conversion in the next 20 years, at least--once all the baby boomers die out it may happen, but I still have doubts it'll happen in my lifetime. While I agree it is somewhat annoying, it didn't take me but a few weeks at BAF to learn all the conversions by heart--complaining about it seems as futile as expecting shady companies to stop making knockoffs.

    The problems is, us europeans-asian-african have to learn a different (& not so useful) metric system just because of you..

    But that's how the world works
