Ok let's put this "A pint's a pound the world around" statement to bed.
That's at best an approximation used by cooks. First of all it applies
to liquids that are mostly water. Even milk is denser, and weighs more,
then plain water. Also the density, and hence the weight per volume, of
anything changes with temperature and altitude (barometric pressure).
Besides that a U.S. gallon is defined as 231 cubic inches and a U.S.
gallon of fresh water at sea level at 72 degrees Fahrenheit weighs 8.345
lbs. This comes to 1.043 lbs per pint under the specified conditions.
The imperial gallon (the UK system before they went metric) is defined
as 10 pounds of pure water at 62 degrees Fahrenheit at a barometric
pressure of 30 inches of mercury. The measure must be taken on scales,
with the water suspended in the air and measured with brass weights. In
the imperial system, with 8 pints in a gallon, a pint is 20 fluid
ounces, so a fluid ounce of water does weigh one ounce exactly under the
prescribed conditions).

OK OK OK I yeild. But a PINT in US Liquid measure is still 16 FLUID OUNCES.
