Not in this universe. joules does not = watts any more than miles per hour 
= miles.
Joules and miles are quantities (energy and distance). Watts and mph are 
the RATES at which the quantities are being expended. The 5.625 joules, if 
and only if expended over exactly one second, yeilds 5.625 watts of power.
therefore,

5.625 Joules per bang X 120 bang/sec= 675 joules/sec = 675 watts.
  Watts per second would be the rate at which  energy use was accelerating, 
but that has no meaning in this context.

joules :^/

Well, I can't figure out where the number 795 came from! 120 x 5.625 = 675

A most elegant understatement.
