Recently I have taken an interest in physical constants (and, through it, an interest in SI units and the upcoming redefinition of the kilogram). I actually have a list of almost all of them now, standard uncertainties included. After a bit, I decided to have a bit of fun messing around with the constants just to see what popped out. Upon dividing planck length by planck time, I was surprised and intrigued to discover that the answer is the speed of light. I then began to wonder if there could possibly be other relations like this that, using planck units, give such constants. Planck energy times planck time gave me the reduced planck constant, 1.0545717×10-34 J×s. Planck length cubed divided by the product of planck mass and planck time squared gave me the gravitational constant, 6.67384×10-11. But oddly, upon dividing planck energy by planck temperature in an attempt to arrive at the boltzmann constant, I hit a... strange roadblock. The boltzmann constant DID technically come out the other side... but it came out 1064 times larger than it should have. Instead of 1.38065×10-23, I was getting 1.38065×1041. Why is this?
