No kidding, it is possible to convert, but...
To figure out the diameter in millimeters, with x standing for the AWG gauge: Take the 39th root of 92. Then raise this to the power of (36-x), keeping in mind the goofy negative numbers for those big AWG gauges. Multiply the result by 0.127 to get diameter in millimeters. If you want Fred Flintstone units, figure out the proper number to use in the last step yourself. You won't get rid of that 39th root, however.
