Hi, I’m Tristan McCauley from Lucky 7 Tattoo,
and I’m here to talk to you about converting gauges to millimeters. Let’s take for instance
an 18 gauge piece of jewelry. What you want to do is take a small length of string, go
around the circumference of that piece of jewelry. You then measure that in inches.
So, an 18 gauge is .125 inches. You then multiply that by pi, which is 3.14. And you get .4
to 0. There are twenty five millimeters in an inch, so, you multiply 25.4 by a .40, and
you get 1.02 millimeters, so in essence, an 18 gauge is equal to 1.02 millimeters. This
rule applies to just about any size jewelry, from a two gauge, up to a half inch. Just
measure it, multiply it by pi, and then go from there. And that is how you convert body
jewelry from gauges to millimeters.
