One cubic foot of water weighs about 62.4 pounds.
The weight of 2.25 cubic feet of water is approx 4495 pounds-force (lbf).
Approximately 102 pounds for 1.63 cubic feet of water (12.2 US gallons).
244 cubic feet of what?
If the weight is 62.5, then it weighs 62.5
Approximately 1,775.9 pounds.
800 cubic feet of water weights roughly 49,941.52 (water volume times density.)
The weight of any volume of water will depend on the gravitational force acting upon it. 57 cubic feet of water would weigh nothing in a spaceship, for example.
The weight of 0.4 cubic feet depends on the density of the material. To convert volume to weight, you need to know the specific density. If we assume an average material density of 100 lbs/cubic foot, then 0.4 cubic feet would weigh 40 lbs.
Cubic feet can't be converted to pounds. Cubic feet measure volume, while pounds measure mass.
2.5 cubic feet of water weighs about: 156 pounds.
100 cubic feet = 2831.7 litres.
2.3 million cubic feet of water is approximately 17.2 million gallons.
