Orders of magnitude (entropy)

The following list shows different orders of magnitude of entropy.

Factor (J K−1) Value Item
10−24 9.5699×10−24 J K−1 entropy equivalent of one bit of information, = k ln 2[1]
1 5.74 J K−1 standard entropy of 1 mole of graphite[2]
1033 ≈ 1035 J K−1 entropy of the Sun (given as ≈ 1042 erg K−1 in Bekenstein (1973))[3]
1054 1.5 × 1054 J K−1 entropy of a black hole of one solar mass (given as ≈ 1060 erg K−1 in Bekenstein (1973))[3]
1081 4.3 × 1081 J K−1 one estimate of the theoretical maximum entropy of the universe[4][5]
