Dear Jim, Check: http://w3.uwyo.edu/~metal/gage.html as a starting list for wire gauges.
I particularly like the writer's discussion of the spelling of gauge vs gage and then the definition of gage. 'Gage: An arbitrary assignment of numbers to size, used on sheet, wire, and many other things (tubing, shotgun bore, needles, and so on). Unfortunately there are so many different standards that using gage to specify a material is almost useless, and perhaps even dangerous. If in doubt, use decimals'. I would change the final sentence to read 'If in doubt use micrometres', but otherwise I agree that gauges (or gages) are relatively useless. By the way, I noticed that they made an error with respect to 'Card Wire Gauge CWG' which they say is for fibre yarns when it is, in fact, used for the specialised metal 'wires' that are used on the rollers and drums of carding machines. These are actually not circular wires but rather flattened strips of metal with raised pins designed to engage with textile fibres as they are being 'carded' (Note: Textile carding is a sort of rough combing process).
