kJ to Watts calculator

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

kJ to watts calculation

Energy in kJ
Time period in sec

P(W) = 1000 x E(kJ) / t(s)

The power P in watts (W) is equal to 1000, multiplied by the energy E in kilojoules (kJ), divided by the time period t in seconds (s).
