What is the mass of fresh water per cubic foot in ounces?

Answer 1

By definition, an imperial gallon of water weighs 10 pounds. 1 cubic foot is 6.22883 imp gal, so 62.2883 pounds. 16 ounces in a pound, so we get 62.2883x16 = 996.6128 or about 997 ounces.

Using a different sequence of conversions gives 999 ounces. The answers vary because the density of water varies with temperature.

Answer 2

Each cubic inch of water weighs roughly two thirds of one ounce. To prove this statement, the following:

One fluid pint is made of 16 fluid ounces. The [cubic inch] volume of a pint is 28.8750000001267 cubic inches (which to simplify matters, we will round this number to the nearest thousandths place; doing so gives us the easier used number 28.875). If we use water for the density (the constant being that the water is purified, and has the temperature of 34*F, and is at sea level), the answer becomes 0.554 (roughly 2/3) ounces per cubic inch of water.

Answer 3

1cu ft = 12 * 12 * 12 cu.in = 1728 cu in = 1728 * (2.54*2.54*2.54) cc = 28316.85 cc = 28.3 liters = 28 kg or 62.4 pounds

Answer 4

One gallon of distilled water weighs 8.33 lbs.

Answer 5

One cudic foot of water weighs 62.5 lbs.

Answer 6

A cubic foot = 7.48 US gallons.
