Electric current in amps (A) to electric power in watts (W) calculator.
Select current type, enter current in amps, voltage in volts, power factor for AC circuit and press theCalculate button (DC = Direct Current, AC = Alternating Current):
* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12
Watts to amps calculator ►
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)
