Abstract
Starting from entropy in equilibrium thermodynamics, defined as the mean value of a bit-number, the cumulants of this bit-number are discussed. Moreover, relative bit-numbers of two probability distributions, and their cumulants are considered. All these cumulants are additive quantities for independent systems, and are invariants with respect to reversible motion. The cumulants of lowest order are well known quantities in statistical thermodynamics, which play important roles in nonequilibrium thermodynamics as well. Their reversibility invariance gives a justification of the macroscopic approximation by “local equilibrium” for hydrodynamic system on a very general level.
