Gauge To Millimeter Conversion Chart
We receive a lot of emails asking what size people should gauge to next when gauging their piercings. We also recieve a lot of emails from our U.K., Australian, Canadian and other international customers asking what the gauge to millimeter conversion is for our jewelry. We decided to make an easy to read chart to clarify these questions. The gauges are listed from smallest diameter to largest with standard gauges in the left column and the millimeter conversion for the corresponding gauges in the right column.
Here is the chart:
| Gauge | Millimeters |
| 18G | 1.0mm |
| 16G | 1.2mm |
| 14G | 1.6mm |
| 12G | 2.0mm |
| 10G | 2.5mm |
| 8G | 3.0mm |
| 6G | 4.0mm |
| 4G | 5.0mm |
| 2G | 6.0mm |
| 0G | 8.0mm |
| 00G | 10.0mm |
| 7/16″ | 11.0mm |
| 1/2″ | 12.0mm |
| 9/16″ | 14.0mm |
| 5/8″ | 16.0mm |
| 3/4″ | 19.0mm |

I typically wear 18 ga nose screws or retainers. I am finding it difficult to find 14k gold nose screws online that I don’t have to either 1) stretch the curved part out farther in order to get it into the hole or 2) sand the end down so that it doesn’t scratch when it goes into the whole. Is there anyway to judge these before ordering and being stuck with something I can’t wear or return?
