Planck units

pne*snicker* Just found this page on Everything2 to do with "Planck units".
Why use kilograms? Why pounds? They're all pretty arbitrarily defined. But some constants are given (e.g. the speed of light in a vacuum, the gravitational constant "big-gee", etc.) so one could derive "logical" units from those.
Their order of magnitude may not be very useful without scaling them up or down, but ... well, read the write-up.
