Energy Converter

Energy Conversion refers to the ratio between the output and input of an energy conversion machine in terms of energy only. The useful output may be electric power, mechanical work, or heat. It is the process of changing energy from one form to another.

According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form. Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat at the point of collision.

The SI unit of energy is the joule (J) or newton-meter (N * m). The joule is also the SI unit of work.

Formula
1 attojoule = 2.39005736 × 10-19 calories

P = IE
P = Power (Watts)
I = Current (Amps)
E = Voltage (Volts)

So: I= P/E
E = P/I
1 Watt = 1 Ampere * 1 Volt

The process of changing one form of energy into another, such as nuclear energy into heat or solar energy into electrical energy is termed as energy conversion. One calorie is about 4.2 joules.
Energy conversion efficiency is not defined uniquely, but instead depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle.
\eta = \frac{P_\mathrm{out}}{P_\mathrm{in}}

Example:
Convert the energy for the given details. For given attojoule into calorie.
Convert value = 5 attojoule
Convert to = Calorie (I.T.)

Solution:
Calorie (I.T.) = 1.1942294831374797e-18
