What's a Watt Thermal?

Obviously a watt Thermal is a unit of heat energy, expended as electrical energy is converted into "work" of some kind... But how does it relate to processors?

For example, A conroe processor has a TDP of 65w... It's a quantitative value, and not a rate... so how does this relate to a BTU? Is it the same way a Fridge runs at xKW/hr? A watt is temporal unit lasting one second... And that's what confuses me... Obviously a Conroe processor doesn't put out 243 000w of heat /hr... Sigh.

A BIP 240 Radiator can dissipate about 1100 BTU/HR of heat energy. That's about 325w of energy. Can this wattage be... well, incorrectly transformed into a Rate? 325w / hr?

I'm assuming that, via this simplistic calculation a BIP 240 radiator could dissipate the heat of about 5 conroe processors... But i'm not sure as I don't know how well a watt converts into a rate (btu/hr).

Any insight would be helpful, I'm kinda going crazy trying to logically figure this out.
 
This article may answer most of your questions about TDP (specifically pages 2 and 3). I still think that most people don't know the difference between how Intel and AMD calculate TDP...
 
That's interesting... I didn't know there was a difference...

I guess my main question, to summarize is:

How does TDP relate to a Radiator's BTU/hr capacity?

Or rather, does a heat output of 65w = 225 btu/hr
