American wire gauge is better. They defined zero as 8.251 mm diameter so for thicker wires they had to use multiple zeros. And for some reason many Americans write it as (1/0) which looks like one divided by zero. And its pronounced "one aught." It also has no resemblence to barrel gauge for firearms even though they follow a similar principle of increasing gauge leading to decreasing diameter. For example a 12 gauge shotgun barrel is much larger than a zero gauge wire. Interestingly firearm gauges never hit zero.
