Watts to amps calculator

We are offering the electric power in watts (W) to electric current in amps (A) calculator, you can simply make calculations. Enter the value of current type, enter power in watts, voltage in volts, power factor for AC circuit and press the = button which can be called as DC = Direct Current and the AC = Alternating Current.

DC watts to amps calculation

The value of current I measured in amps (A) is apparently equal to the value of power P in watts (W), which is divided by the value of voltage V in volts (V).

I_(A) = P_(W) / V_(V)

AC single phase watts to amps calculation

The value of phase current I in amps (A) is apparently equal to the value of power P in watts (W), which is divided by the value of power factor PF multiplied by the RMS voltage V measured in volts (V).

I_(A) = P_(W) / (PF × V_(V))

The value of power factor of the resistive impedance load is apparently equal to 1.

AC three phase watts to amps calculation

Calculation with line to line voltage

The value of phase current I in amps (A) is apparently equal to the value of power P in watts (W), which is divided by square root of 3 multiplied by the power factor PF times the value of line to line RMS voltage V_L-L measured in volts (V).

I_(A) = P_(W) / (√3 × PF × V_L-L(V) )

The value of power factor of the resistive impedance load is apparently equal to 1.

Calculation with line to neutral voltage

The value of phase current I in amps (A) is apparently equal to the power P in watts (W), which is divided by 3 multiplied by the power factor PF times the value of line to neutral RMS voltage V_L-N measured in volts (V).

I_(A) = P_(W) / (3 × PF × V_L-N(V) )

The value of power factor of the resistive impedance load is apparently equal to 1.

Typical power factor values

You are not required not to use the typical power factor values for the accurate calculations.
