Talk:Engineering Tables/Standard Wire Gauge

inaccurate information
The information on the ohms per 1000 foot lenghts is incorrect. The values appear to be off by a factor of 10.

I completely agree. A kilometer is more than a foot so the ohms per 1000 feet cannot be greater than the ohms per kilometer

The wire gauge diameters and mass/length appear to be off by ~1 gauge as compared with all other sources I have found. See https://en.wikipedia.org/wiki/American_wire_gauge for gauges that are consistent with other sources. Steve M

Tolerances for specified quantities?
The word "engineering" in the title would appear to me to demand tolerances on all specified parameters, such as wire diameter. Otherwise, the quantities seem meaningless. For example, what prevents vendors from selling "18 AWG" copper wire that has a diameter closer to 19 AWG? If there are no mandated tolerances, could they say that "it's within industry tolerances"? As the copper material dominates the cost of production, this would be a great way to increase profits! Of course, I tried to google such tolerances, but found nothing.
