They are measurements of wire size in AWG, or American Wire Guage. You can find a wire guage chart here: http://www.cobrawire.com/charts.htm#AWG Which gives the diameter of the wire in inches and millimeters, its circular area, and weight. To my (limited) knowledge, AWG is a fairly universal standard, though this chart shows AWG, W&M, SWG, BWG, US Standard. http://www.calfinewire.com/services/wirech.htm -Adam Tal Bejerano - AMC wrote: >Hi 2 All > >I found many circuits that talking about "#16 wire" or "#8 Screws" "22 gauge >wire". what are this measurements? >where can I find converter for this measurements? > >Thanks > >Tal > >-- >http://www.piclist.com hint: The PICList is archived three different >ways.
