Electric current in amps (A) to electric power in watts (W) calculator.

* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12

The power *P* in watts (W) is equal to the current *I* in amps (A), times the voltage *V* in volts (V):

*P*_{(W)} = *I*_{(A)}* *×* V*_{(V)}

The power *P* in watts (W) is equal to the
power factor *PF* times the phase current *I* in amps (A), times the RMS voltage *V* in volts (V):

*P*_{(W)} = * PF *×* I*_{(A)}* *×* V*_{(V)}

The power *P* in watts (W) is equal to square root of 3 times the power factor
*PF* times the phase current *I* in amps (A), times the
line to line RMS voltage *V*_{L-L} in volts (V):

*P*_{(W)} = *√*3
× * PF *×* I*_{(A)}* *×* V*_{L-L(V)}

The power *P* in watts (W) is equal to 3 times the
power factor *PF* times the phase current *I* in amps (A), times the line to neutral RMS voltage *V*_{L-N} in volts (V):

*P*_{(W)} = 3 × * PF *×* I*_{(A)}* *×* V*_{L-N(V)}
