Web site with lots of info on SWG vs BWG. The differences are so close that they are below manufacturing tolerances.

Way BITD when I was doing my research on bicycle tubing I made up this conversion sheet between BWG, MM & Inch dimensions because that's whats was being used by some sources. Note dot matrix printer.

I wasn't aware that Reynolds changed from BWG to SWG until you brought it to my attention. Also, the SWG standard was discontinued and changed to "mil" .001".

It's now more sensible MM millimeters.
