1 gallon of water is equal to: 0.1337 cubic feet.
1 cu ft = 0.037037 cu yeard
Approx. 36.38 cu. ft of vapor per gallon @ 60 deg. F, check this url http://www.patioheat.com/lp_gas.htm
7.481 gal - 1 cu ft; 17,000 gal = 2,272.42 cu ft
AnswerOne Gallon of LPG (liquefied petroleum gas) will expand to 35.79 cubic feet of propane gas at 1 atmosphere of pressure.
.1337 cu ft / gal 7.481 gal / cu ft
One Imperial gallon is 0.1605 cubic feet.
28 gallons (UK) = 4.5 cu ft
The answer is specific to the product in the cu ft. A cu ft of water will be different than that of a cu ft of feathers ETC.
volume = pi * r 2* l = 3.1416*1.252 * 500 = 2454.375 cu ft 1 cu ft = 6.2288 imp gallon 2454.375 cu ft = 15287.811 gallons or say 15288.
2 Imperial gallons = 0.3211 cu ft (to 4 sig fig)
1 Imperial gallon = 0.1605 cu ft (to 4 sig fig)
1 Imperial gallon = 0.1605 cu ft (to 4 dp) 1 US gallon = 0.133681 cubic feet
1 cu. ft. = 28.32 liters
You can't do that. Cu Ft is volume and Ft is length - the units are not the same.
If you meant cu. in to cu. ft.divide by 1728.
The answer to your question is: No.The gallon is a unit of volume.A gallon can have different masses, depending on what's in it.And if the gallon is empty, then it has no mass at all.Weight depends on the mass and the acceleration of gravity where the mass is.The same mass doesn't even always have the same weight.
