kW to Joules calculator

Enter the power in kilowatts (kW), time period in seconds (s), then press the Calculate button to get the result in joules (J).

kW to joules calculation

Power in kW
Time period in sec

E(J) = 1000 x P(kW) × t(s)

The energy E in joules (J) is equal to 1000, multiplied by the power P in kilowatts (kW), multiplied by the time period t in seconds (s).
