I have seen the online calculators, but would like to see how the formula works in full detail. I have seen the kilograms / meters / second example already.
The second part of the question is, what is the actual formula for converting foot pounds of force to Newton meters? Again, the actual details. Thanks...

If you wanted to, you could multiply the individual conversion factors to get there. That is, the conversion meters to feet and Newtons to lbs (of force) and get the same number. Is this what you are asking about or did I misunderstand your question.

Thanks!
I am looking to convert 1 kilogram of mass into footpounds using e=mc^2 and without any unnecessary conversions. I want to see how the final number is arrived at. I then want to see how footpounds are converted back to newton meters, which are more typical for e=mc^2. Again, I know there are online calculators, but they don't educate the mind :)

Calculating e=mc^2 using footpounds of force
In the spirit of teaching a man how to fish versus simply giving him a fish, it looks like you might benefit from a tutorial on "how to convert units". Here's the first one I found with a Google search on that phrase:
