Interesting, but here is a different one (I think it was provided by Bob Lee):
This gives:
AWG 8 = 8,4 mm^2
AWG 10 = 5,3 mm^2
12=3,3
14=2,1
16=1,3
18=0,8
20=0,5

So which one is correct??

Thanks for the link. I added the CoilCraft data to my spread sheet.

Oops, both are correct - sorry.
I've overlooked that it is mm in one case and mm^2 in the other...

Ive found a much better one. Its a PDF file, so you need acrobat reader. But it converts AWG directly to mm^2, so its a lot more useful. Plus its much more professional looking than the last one I posted.

Check it out:

This time I'm pretty shure that the coilcraft and balluff data do not correspond....

But as the coilcraft data correspond to the formula provided by Bob Lee (QSC) I suppose the Balluff data are wrong.

Or have I overlooked something again?

Well, I think that the new data is correct. Bob Lee's forumula may not have been that accurate.

Either that or this one just gives rough comparison, like 12 gauge is roughly 4mm^2 or something like that.

We should probably ask someone who actually knows

According to Table 12-1 in the Handbook for Sound Engineers:

6 AWG = 13.3 mm^2
8 AWG = 8.36 mm^2
10 AWG = 5.26 mm^2
12 AWG = 3.31 mm^2
14 AWG = 2.08 mm^2
16 AWG = 1.31 mm^2
18 AWG = 0.82 mm^2
20 AWG = 0.52 mm^2
22 AWG = 0.33 mm^2

Bob,

Thanks! I updated my spread sheet too.
