Wire Gague Calculator.
Source code supplied by: Gerald Newton, www.electrician.com.

The following calculator calculates the voltage drop, and voltage at the end of the wire for American Wire Gauge from 4/0 AWG to 30 AWG, aluminum or copper wire.
Note: It just calculates the voltage drop, the voltage drop does not depend on the input voltage, just on the resistance of the wire and the load in amps.
