Is there any quick formula to convert joules into watts? This would solve an argument at work.

KWH = 3,600,000 joules

Thanks guys, the argument was trying to decide how much in watts 360 joules of defibrillator power equaled out to in watts. My friend (also an electrician) whom I am partners with at EMS, and I sure got some weird looks from the rest of the crew while arguing our points. I don't think the rest of them even had a clue.

There is no direct equivalent—watts are units of power and joules are units of energy.

1 joule = 1 watt∙second,

so 360 joules would be 360 watts flowing for one second, or 3600 watts flowing for 0.1 second, et cetera.

Applying Ohm's Law to human organs to determine voltage for a given current through human tissue gets complicated quickly.

A capacitor can store and release joules {energy} but watts are a unit of power, so with watts you have to define a time interval to derive/equate energy.
