Orders of magnitude (entropy) explained

The following list shows different orders of magnitude of entropy.

Factor (J⋅K)	Value	Item
		Entropy equivalent of one bit of information, equal to k times ln(2)^[1]
		Boltzmann constant, entropy equivalent of one nat of information.
		Standard entropy of 1 mole of graphite^[2]
	≈	Entropy of the Sun (given as ≈ in Bekenstein (1973))^[3]
		Entropy of a black hole of one solar mass (given as ≈ in Bekenstein (1973))
		One estimate of the theoretical maximum entropy of the universe^[4] ^[5]
