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. This is the product of Force (in Newtons) and Distance (in meters) Energy is usually measured in terms of heat, which is measured in calories or joules The SI unit â¦ of energy is the Joule. In the ft lb system it is ft.lbforce. 1 ftlbf = 1.356 joule.or example, when a machine operates, some mechanical energy is lost to heat energy. The ratio of mechanical energy conserved to the energy lost to thermal energy is known as efficiency, and no machines have 100% efficiency (no heat loss).
