how do I figure the cost of watts?
Can you help me figure this out. I know it should be fairly simple but I just don't seem to get it. Lets say I have a Kill A Watt. I plug something into that Kill A Watt and it reads 55 watts. How ...

The engineer in me likes to reinforce SI units since they are used almost everywhere in the world.
From having read your many informative posts, I know you know them, and I wasn't really just yanking your chain :)
I was actually trying to point out how closely the commonly used KWH energy units are to the SI Joule energy units you were referring to.
It's the fact that the common unit and the SI unit are basically the same, which brought about my post. That close relationship is relatively unusual, since most commonly used units in the U.S. are not related to SI units: miles, feet, inches, BTU, degrees F, etc.
A Joule is a watt-second so the commonly used KWH is directly obtainable by knowing the number of seconds in an hour (3600=60*60) and the number of watts in a kilowatt (1000) to get the 3.6 megajoules = 1 KWH conversion.
I'm just busting on you, and I know you know your stuff as well. Take care and keep the helpful post coming!
