AWG = American Wire Gauge size from 1 to 40
Dia-mils = Diameter in mils (1 mil = .001 inch)
TPI = Turns Per Inch [Note that this is for ENAMEL INSULATION. Insulation thickness varies]
Dia-mm = Diameter in millimeters. 
Circ-mils = Cross sectional Area in Circular Mils. ( circular mils = diameter in mils squared )
Ohms/Kft = Ohms Per 1,000 ft.
Ft/Ohm = Number of feet required for 1 Ohm of resistance
Ft/Lb = Feet Per Pound
Ohms/Lb = Ohms Per Pound
Lb/Kft = Pounds Per 1,000 feet
*AMPS = Conservative Amp Rating based on 750  circular mils per Amp
Max Amps = Maximum allowable current based on 500 circular mils per Amp. Do NOT exceed this rating.
