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.
joule. 1. A unit of work or energy transfer. One joule is equal to work done by a force of one newton moved about 1 m in the direction of the force. 2. (J) A unit of energy equal to the work done when a force of one newton is applied through a distance of one meter. Used instead of calorie: 1 J = 0.239 cal.
