John, Here is one link to a Coilcraft site and three links to Alpha Wire &Cable's site. It looks like you are possibly dealing with 46 gauge wire, or even 44 gauge, and you might want to take another look at the exact measurements based on these charts. This Coilcraft link seems to agree pretty much with the link provided to reawire in a previous post, although these charts only cover solid wire, and not stranded, as it appears that you need. ===> http://www.coilcraft.com/awg.cfm ===> http://www.alphawire.com/pages/341.cfm ===> http://www.alphawire.com/pages/379.cfm ===> http://www.alphawire.com/pages/380.cfm Based on what I see by looking at the above charts, it appears that your particular stranded wire may not be in accordance with the standard AWG (American Wire Gauge) table, and might be fabricated to some other "gauge". It may possibly be made to a "MIL" spec, although I am pretty sure that they also conform to the "AWG" standard. Please note that some "MIL" spec wires do in fact have a large number of small strands, and this would possibly be the answer to your specific wire. It occurs to me that there is also a "British Wire Gauge" of some sort, although I have not heard of it in ages. Quite possibly there is also a standard metric "Gauge" or two floating around out there that I am not aware of. Please remember also that wire is measured in "Circular Mils", which is not the same as the "Square Mils" that we are familiar with in dealing with cross sectional area of a copper trace on a PC Board. A "Circular Mil" is only 78% of a "Square Mil". Also, if you do any internet searches, remember to search using the both the spelling "gauge" and "gage", since both are used and both are considered "correct" Hopefully this has been of some help, JaMi A quick search dug up the following additional information, although I am not sure how reliable it is: ===> http://www.reade.com/Conversion/wire_gauge.html ===> http://www.mogami-wire.co.jp/e/cad/wire-gauge.html ===> http://www.raelectrical.com/wire_gauge_conversion_chart.htm ===> http://www.metric.fsworld.co.uk/siwire_elect.htmhttp://www.metric.fsworld.co .uk/siwire_elect.htm ===> http://www.pianoworld.com/wire_conversion.htm * * * * * * * * * * ----- Original Message ----- From: "Grabski III, John R." <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, June 17, 2003 4:31 AM Subject: [TN] wire gauge calculation... > Good morning, all... > > Our cable assy plant uses a chart made by T.E.S.L.A. to calculate Circular > Mil Area and wire gauge... and for the most part it is completely useful... > But recently we received in some cable in need of calculation, and our chart > does not go smaller than 29 gauge though...
