Piercing Size Conversion Table

When buying stretching jewellery and other body piercing, it is important to know the diameter of the part of the item that will rest inside the piercing. So what you want to get right here is its thickness.  

In Tribu we measure jewellery using Millimetres, if you're from a country that uses Gauge or Inches to measure Piercing jewellery, this page is for you!
