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

kW to kJ calculation

kJ: 0

E(kJ) = P(kW) × t(s)

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