Gallons are volume, not weight. A gallon is 128 fluid ounces. The word ounce can refer to an ounce of volume (like the fluid ounce mentioned above), or an ounce of weight. An ounce's weight of air will have a greater volume than one gallon.
1 lb = 16 oz
4 lb = 4 x 16 = 64 oz
4 lb is therefore heavier than 58 oz
One pound equals sixteen ounces. So four pounds would equal sixteen times four, which equals sixty-four.
80 ounces is heavier, it equals 5 pounds
4 pounds = 64 ounces. 67 ounces is greater and more heavier.
