Hello. I recently discovered Gerard 't Hooft's (what a complicated name to type, isn't it?*apostrophe*apostrophe*apostrophe) equation for the entropy of a simple black hole (what is meant by "simple" I have no idea). It is:(adsbygoogle = window.adsbygoogle || []).push({});

Where "S" is the entropy of a simple black hole

A is the area of the black hole's event horizon

h is (reduced?) Planck's Constant

G is the gravitational constant

S = A/(4hG)

Unless there is a conversion constant missing in this equation (is there?), I get units for entropy as (s^3)/(m^3).

That is,

Entropy = [m^2]/[(kg*m^2/s)*(m^3/kg*s^2)]

= seconds cubed per meters cubed? What does this signify? Is there some "speed" associated with entropy such that entropy is inversely proportional to the cube of this "speed"?

Or am I way off track here?
