SWG to meter conversion...

could any one tell me a formula to convert wire thickness in SWG into meters ? I have a 30 SWG thick wire and would like to know it's thickness in metres for certain calculations...

Thanks in advance...

If SWG is anything like AWG here in the U.S., you can't use the actual gauge number in a calculation for it is nothing more than a "name" rather than a calculated number. You might as well call each of the succeeding sizes of wire "Ralph", "Henry", "Joe", "Bill", "Mike", etc. vs. #4, #5, #6, #7, #8, etc. Ultimately, you're slaved to a look-up table.

Now, in the U.S., once you're larger than #0000, the gauges revert to the cmil size of the wire, and with that information, you'd have a chance at determining "thickness" or more properly, diameter.

Hiya Loh,
Below is a table of wire data I pulled out a dick smith catalouge it should have everything you need.

Hope it helps
