From your reference.



And my reference:

http://en.wikipedia.org/wiki/Pound-mass

"This article is about the unit of mass. For the unit of force, see
Pound-force.
The pound or pound-mass (abbreviation: lb, lbm, or sometimes in the
United States: #) is a unit of mass used in the imperial, United
States customary and other systems of measurement."



bc suggests Robert read more carefully, and is reminded of Einstein's
dictum: change the facts to fit the theory.

I, too, went thru life (about > 50 years) thinking the pound was a
unit of force. It is not, as pointed out by JD recently.

fine.
