Q.
How many millimeters thick is 21-gauge wire? Is there a conversion chart somewhere on the website? Thanks so much for your help.

21-gauge wire is 0.71mm or 0.028 inches thick. Our Wire Gauge to Inches and Millimeters Conversion Chart is located within the EncycloBEADia, where you can find all sorts of charts and resources for your beading needs.
