i first heard of slugs at age 7, but i've never seen them used in an

we used SI almost exclusively in university and high school. i was
taught
there that pounds is a unit of force (not mass). however Wikipedia
claims
pounds is a standardized unit of mass, not force.


I don't care who says pounds is a unit of mass, they are wrong! If you
use pounds in a formula that wants mass, your answer will be WRONG.


please read the NIST publications which define the Avoirdupois pound in
terms of kilograms. this is not debateable since NIST is *the* authority in
the US.
