Convert from volts (V) to kilowatts (kW) online

Enter the voltage, U, in V (volts)

Enter the current, I, in A (amps):

Power, P, in kW (kilowatts) is:


How to calculate power in kilowatts, if you know the voltage in volts and current in amperes?

To obtain power in kilowatts, it is necessary to multiply the voltage in volts by the current in amperes and divide by 1000 (convert from W to kW)

P = U х I / 1000, where

I is the current in amperes (A);

P is the power in kilowatts (kW);

U is the voltage in volts (V).
