Energy may exist in different forms. It can be light energy, thermal energy, potential energy, kinetic energy, chemical energy, nuclear energy, etc. Every physical matter (or body or thermodynamic system) intrinsically possesses certain amount of energy in one form or another. Such energy can be converted from one form to another for storing it within the same body. It can also be transferred from one body to another with or

Every physical “matter” intrinsically consists of one or more “properties” (such as mass, weight, length, velocity, temperature, current, etc.). By definition, every property of a matter is measurable and quantifiable. Measurement of a property can be carried out with suitable instrument. However, to quantify the measured result, a “magnitude” along with its “unit” is required to present. By definition, a unit of measurement indicates “a standardized and well-defined magnitude of
