Converting Watts to Joules
Watts measure the rate of power consumption, while Joules measure the total energy consumed. To convert watts to joules, you must multiply the power by the time duration in seconds during which the power was applied.
$$ E_{(J)} = P_{(W)} \times t_{(s)} $$
Energy in Joules equals Power in Watts multiplied by Time in seconds.
