Brown and Sharpe Gauge Conversion Chart

This chart is a crucial tool for jewelers wanting to accurately convert from inches or millimeters to the equivalent gauge when purchasing precious metal round wire or flat sheet.

We highly recommend that you print copies for your bench and your computer. This way you are always one glance away from knowing the gauge you want, whether you are hard at work on a piece of jewelry or placing an order on our website.
