kJ to kW calculator

Enter the the energy in kilojoules (kJ), time period in seconds (s), then press the Calculate button to get the result in kilowatts (kW).

kJ to kW calculation

Energy in kJ
Time period in sec

P(kW) = E(kJ) / t(s)

The power P in kilowatts (kW) is equal to the energy E in kilojoules (kJ), divided by the time period t in seconds (s).
