BTW I think a newton or N in this chart is = to one kilo or 2.2 pounds.
A meter of course is 3.28 feet so to convert to foot pounds
multiply N-Meters  by 2.2 and  divide by 3.28 to get foot pounds.
At least I think this is the proper conversion!

F = mg
in english units, lbs. = slugs * 32ft/sec^2
in metric, N = kg * 9.8m/sec^2

1 kg force = 2.2 lbs = 9.8 Newtons

Thanks Perry. Please convert 600 N-Meters to ft pounds for me.
Newtons came along well after my time in school :-)

600 * (2.2/9.8) * 3.28 = 442 ft-lbs.

a Newton is a fraction of a pound, but a meter is more than a foot, so
the numbers aren't that different.

Yes I see the answer came out about the same.

I looked it up in the dictionary and
what they said was the "force which imparts to a mass of
one kilogram, an acceleration of one meter per second per second."

Not too clear!

Then I looked it up in a physics book and a pound 
is equal to 4.45 newtons. One newton is therefore
0.2247 pounds. This is a lot clearer for me.

To simplify divide N-Meters by 4.45 and multiply by 3.28 and you can 
convert N-Meters into foot pounds. 

Or..even better.. merely multiply N-Meters by .737 to get foot pounds.
 
And the mks system is supposed to be easier :-)

Ironically Sir Isaac Newton was an englishman and they
named this force in his honor as a sop to us who prefer the 
english system. After all... HE invented Newtonian Physics
...I think we ought to stick with what he said. 
The Europeons be dammned :-).
