Hmmm..... I always did it like this:

Physical/Energy: (Damage Per Round + Any Added Damage) * (RpS + Any Added Rps) = DPS

Example: (CM 225) (340.0 + 56.4 {Any augs or masteries that add damage}) * (10 RpS + 0 {Any Augs or Masteries that increase Round Per Second}) = Damage Per Second on one target. If you want Multiple targets, times by Pierce at the end.

Thermal/Chemical weapons: [(Damage Per Round + Any Added Damage) + (Combine all DoT and Divide by the number of seconds it takes to deliver full DoT)] * (RpS + Any Added RpS)
