On our site we try to list just about all of the jewelry in inches and millimeters. Even with that there may be times when you need help to put these numbers in perspective. How big will a 1/2 disc charm look when you wear it?

This page is here to provide you with the tools and tips to make measurement and length conversions easy and simple. There is a chart that lists millimeters, inches, closest fraction of an inch, and the closest coin size. We have also included a chart with the dimensions of the most common US coins actual dimensions.
