I have deliberately constructed the word entropy to resemble as much as possible the word energy, since both quantities to be named by these words are so closely related in their physical meaning that a certain similarity in their names seems appropriate to me. As I deem it better to derive the names of such quantities - that are so important for science - from the antique languages, so that they can be used without modification in all modern languages, I propose to call the quantity S the entropy of the body, after the Greek word for transformation, ἡ τροπή. Translation: Searching for a descriptive name for S, one could - like it is said of the quantity U that it is the heat and work content of the body - say of the quantity S that it is the transformation content of the body.

(1999), An Introduction to Thermal Physics, Addison Wesley Longman, ISBN 7-7 The individual entropy terms will not be absolute, but will rather depend upon the standards chosen, and will differ with different standards by an additive constant. If each logarithmic argument were divided by an unspecified standard value expressed in terms of an unspecified standard mass, length and time, these standard values would cancel in the final result, yielding the same conclusion. Strictly speaking, the use of dimensioned arguments to the logarithms is incorrect, however their use is a "shortcut" made for simplicity. The Sackur–Tetrode equation expresses the entropy S. It is named for Hugo Martin Tetrode (1895–1931) and Otto Sackur (1880–1914), who developed it independently as a solution of Boltzmann's gas statistics and entropy equations, at about the same time in 1912. The Sackur–Tetrode equation is an expression for the entropy of a monatomic ideal gas. Expression of monatomic ideal gas entropy
