Hello All;
Antonio stated in part:

A number of parameters can be determined via formulas based on the
AWG wire gauge number:
The ohms per 1000 feet of copper wire is equal to
0.1/(0.793^AWG)
The circular area in mils is equal to
106000./(1.261^AWG)
The diameter in mils is equal to
325.0/(1.123^AWG)
The pounds per 1000 feet of wire for copper wire is equal to
346.62/(1.261^AWG)
The feet per pound of copper wire is equal to
(1.261^AWG) x 3.129
These formulas appeared in TCBA News some years ago.
