Convert joules (J) to watts (W) by entering energy and time values. Quick and accurate calculator for power measurement.
The Joules to Watts Calculator converts energy measured in joules to power in watts by dividing energy by time in seconds. Since watt is the unit of power equal to one joule per second, this calculator helps quickly estimate power output or consumption based on total energy and time. It’s useful in physics, engineering, and electrical systems to understand energy flow and efficiency. Simply enter the energy value in joules and the duration in seconds to get power in watts instantly.
Formula:Power (W) = Energy (J) ÷ Time (s)
