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.
The Joule-Measuring Heat and Work. By definition, one joule is the work done when a force of one newton is used to move an object one meter. 1 J = 1 N-m. Because work can be converted into heat and vice versa, the SI system uses the joule to measure energy in the form of both heat and work.The First Law of Thermodynamics: Conservation of Energy. The first law of thermodynamics states that energy cannot be created or destroyed. A system can gain or lose energy.ecause work can be converted into heat and vice versa, the SI system uses the joule to measure energy in the form of both heat and work.
