Both equations are the same, they are just in different units. Read up on http://en.wikipedia.org/wiki/Gaussian_units" to get a feel for what us going on.

And I hope you realize that these are theoretical constructs because magnetic monopoles do not exist.
 
Actually, the've not been seen (yet). :wink:

Or maybe yes... A couple of times in the news I read about mag-monopoles having been found under very special conditions in exotic materials.
