Wire Gauge Calculator

Determine the correct wire gauge based on current, voltage, and resistance.

Wire Gauge Calculation

Enter the current, voltage, and wire length to calculate the recommended wire gauge.

Formula Used:

The American Wire Gauge (AWG) is determined based on current, resistance, and length.

The wire resistance is calculated using:

Voltage Drop (V) = Current (I) × Resistance (R)

The resistance per meter depends on the wire material (copper or aluminum).
