Just to pound this into the ground a little more...

1 pound force =3D force unit commonly known as a pound

1 pound mass =3D mass that produces 1 pound force in 1 g (32.17 =
ft/sec^2)=20
gravitational field

1 slug =3D mass that accelerates at 1 foot/sec^2 when acted on by=20
1 pound force

1 poundal =3D force required to produce a 1 foot/sec^2 acceleration
of a 1 pound mass

With units like this, who needs SI?
