I looked at a table with AWG to mm&#178 conversions and it occured to me the sizes are very close to each other. If you fit the AWG to a metric size: E.g. #18 to 0.80 mm&#178, #17 to 1.00 mm&#178 and #16 to 1.25 mm&#178 you end up with something that is only five percent or less smaller than the true value.

As I know that these 1.25 mm&#178, 2.00 mm&#178 etc. sizes are used in some countries, I got the idea to devise a new wire gauge. Let's call it MWG, Metric/Metricated(???)/Metrified(???) Wire Gauge.

The scale then goes like this:

30______0.0500 mm&#178
29______0.0630 mm&#178
28______0.0800 mm&#178
27______0.100 mm&#178
26______0.125 mm&#178
25______0.160 mm&#178
24______0.200 mm&#178
23______0.250 mm&#178
22______0.315 mm&#178
21______0.400 mm&#178
20______0.500 mm&#178
19______0.630 mm&#178
18______0.800 mm&#178
17______1.00 mm&#178
16______1.25 mm&#178
15______1.60 mm&#178
14______2.00 mm&#178
13______2.50 mm&#178
12______3.15 mm&#178
11______4.00 mm&#178
10______5.00 mm&#178
9_______6.30 mm&#178
8_______8.00 mm&#178
7_______10.0 mm&#178
6_______12.5 mm&#178
5_______16.0 mm&#178
4_______20.0 mm&#178
3_______25.0 mm&#178
2_______31.5 mm&#178
1_______40 mm&#178
0_______50 mm&#178
00______63 mm&#178
000_____80 mm&#178
0000____100 mm&#178
