- Which basis of the logarithm underlies the usual formula for Bekenstein-Hawking entropy?

In textbooks, Bekenstein-Hawking entropy of a black hole is given as the area of the horizon divided by 4 times the Planck length squared. But the corresponding basis of the logarithm and exponantial is not written out explicitly. Rather, one oftenly can see drawings where such elementary area is occupied by one bit of information. Thus, I would conclude that the basis of the logarithm and corresponding exponential is 2. Is this correct?

One can express the black hole entropy in vintage units simply by multiplying by Boltzmann‘s constant. In this constant, is there embedded the change of basis of the logarithm from 2 to Euler’s number ##e##?

Thank you very much in advance
