Understand power and energy. Watts are a measure of power, or how fast energy is used (energy over time). Joules is a measure of energy. In order to convert from watts to joules, you need to specify a length of time. The longer a current flows, the more energy it uses.
For instance, in SI units, energy is measured in joules, and one joule is defined mechanically, being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton.
