Trouble with pound-mass (lbm) and pound-force (lbf) is that to make F=MA
work out, you need to keep another 'conversion factor', the dreaded
g-sub-c (g-sub-c = 32.2 lbm-ft / lbf-s^2), around and figure out when to
throw that into the mix.



Really gets to be fun when working with things like foot-pounds,
as in torque, angular momentum, and the pressure due to a certain depth of
water.

Trying to remember when the pounds are mass and when they are force gets
to be fun.
