[vzeaqqxu] Binary powers of Planck units

Someday, when we finally switch over to the one true system of measurements, Planck units, we'll be able to mock our metric brethren about their silly system based on arbitrary measurements of the Old Planet and the number of "fingers" possessed by the Old Species.  In preparation for our switchover, here are some conversion factors for some of our favorite units.  There seems to be some disagreement over the Planck charge: I've arbitrarily chosen the electron.

where:
planckacceleration = planckspeed / plancktime
planckarea = plancklength^2
planckcharge = e
planckcurrent = planckcharge / plancktime
planckdensity = planckmass / planckvolume
planckenergy = planckforce plancklength
planckforce = planckmass planckacceleration
planckgasmileage = plancklength / planckvolume
plancklength = plancktime c
planckmass = sqrt(hbar c / G)
planckpower = planckenergy / plancktime
planckpressure = planckforce / planckarea
planckspeed = plancklength / plancktime
plancktemperature = planckmass planckspeed^2 / kboltzmann
plancktime = hbar / planckmass c^2
