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] |
