The energy E in kilojoules (kJ) is equal to the power P in watts (W) times the time period t in seconds (s):
E(kJ) = P(W) * t(s) / 1000
Kilojoules = Watts * Seconds / 1000
kJ = W * s / 1000
Find the energy consumption of an electrical circuit that has a power consumption of 300 watts given a time duration of 3 seconds.
E(kJ) = 300W * 3s / 1000 = 0.9kJ
