Enter the power in watts (W), time period in seconds (s), then press the Calculate button to get the result in kilojoules (kJ).
Watts to kJ calculation
kJ: 0
E(kJ) = P(W) × t(s) / 1000
The energy E in kilojoules (kJ) is equal to the power P in watts (W), multiplied by the time period t in seconds (s), divided by 1000.
