Dear Dave:
There is a difference between fluid ounces (volume) and ounces of
weight.
There are 12 troy ounces in a pound of gold. Although a troy ounce is
heavier (in grams) than an avoirdupois ounce, a pound of water still
weighs more than a pound of gold. One close relationship that is easy
to remember is, "A pint's a pound -- the world around!" Except in
England.

=Pound=
A unit of Weight defined as the basic unit (instead of Mass) in the
Imperial system. It corresponds to a Mass of 453.592 g, and a Weight of
1 lb = (0.453592 kg)(9.80665 m/s2) = 4.448
