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, equal to k times ln(2)[1]
10−23	1.381×10−23 J⋅K−1	Boltzmann constant, entropy equivalent of one nat of information.
101	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]
