According to Clausius, the entropy was defined via the change in entropy S of a system. Entropy can be thought of as a potential and temperature (or its inverse, rather) as a generalized force associated with displacements along energy dimensions in the entropy potential. Units of Entropy The SI unit for entropy is J/K. Entropy is related to q, the heat flowing into the system from its surroundings, and to T, the absolute temperature of the system.The important properties for this discussion are: 1. J/K) used for entropy in the thermodynamic definition follow from a historical association with heat transfer under temperature gradients, in other words, the definitions of temperature and entropy are intertwined, with entropy being the more fundamental property. The state function entropy S puts the foregoing discussion on a quantitative basis. The Entropy Change of a thermodynamic system is represented as S. If the entropy generation is taken per unit time and per unit volume.

There are various units which help us define Specific Entropy and we can convert the units according to our requirement. Specific entropy is the entropy per unit mass of a system. First the units of entropy are Joules per Kelvin but the degree of disorder has. Specific Entropy conversion helps in converting different units of Specific Entropy. A positive value indicates an increase in entropy, while a negative value denotes a decrease in the. A uniform entropy generation rate corresponds to either minimum energy costs for a. Entropy is probably the most misunderstood of thermodynamic properties. Usual units of standard molar entropy are joules per mole Kelvin (J/mol·K).

The units of of energy over temperature (e.g. Standard molar entropy is defined as the entropy or degree of randomness of one mole of a sample under standard state conditions.
