Joules to Watts calculator

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

Joules to watts calculation

Energy in J
Time period in sec

P(W) = E(J) / t(s)

The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s).
