Wire Gauge Conversions To Millimeters and Inches

Getting the right size wire is vital when buying supplies for your jewellery making projects. You want to be sure that the wire is the perfect size for your design. As with many measurements, our friends in America have a different system for measuring and when it comes to wire they use gauge.

Sometimes, when following projects from the internet or books, this measurement is used. We have created this handy wire gauge conversion chart showing the AWG, American Wire Gauge, sizes and their equivalents in both inches and millimetres.

Below this chart is an example of the different metal wires we provide which come in a wide range of measurements from 0.2mm to 4mm.
