Answer 2

After reading some of the offered answers to your question I am amazed that so few really know the answer: What is an Imperial gallon anyway? On the SAE scale water weighs in at 8 pounds per gallon. Or 2 pounds per quart. Or 1 pound per pint. Or 1 ounce per ounce.

Answer 3

Sorry, but it still weighs a pound, however because it is surrounded by water it will have environmental weight of zero, it won't sink and it won't float up assuming it has the same density and temperature of the surrounding water. but I think what you are most likely concerned with is what mass does it have as this will affect it's movement through the water and how much energy it takes to move it around.

Answer 4

It depends on the temperature of the water. You can check online and get a water table that will list the specific weight of water at the certain temperature you have. Find the volume of water you have and multiply by the specific weight. Your answer will come out usually in lb.m (pound-mass). You will then need to multiply that number by 32.2 to get the weight in lb.force (pound-force).

A kg per liter or a pound for each pint.

Answer 9

1 g per cubic centimeter.
x
2.205 pounds per 1000g
x
(2.54 cm)^3 per in^3
=
You do the math. That'll give you pounds per cubic inch
Divide by 16 if you want ounces.

Answer 10
