"Gallon" tells how much space it fills. "Pound" tells how heavy it is.

Every substance has a different conversion.

-- A gallon of air weighs a small fraction of one pound.

-- A gallon of water weighs about 8.3 pounds.

-- A gallon of lead or stones weighs a lot more pounds.

-- A completely empty gallon weighs zero pounds.
