As stated, Watts and gallons are not the only required inputs. The WPG formula is worth just as much as the inch per gallon IMO. Nothing. There are no "types" of wattage. A watt is a known value. http://en.wikipedia.org/wiki/Watt. Post a specific question if you would like one answered. Google and Wikipedia are good resources to start off with.
