AnswerOne Gallon of LPG (liquefied petroleum gas) will expand to 35.79 cubic feet of propane gas at 1 atmosphere of pressure.
3,366.23 cubic feet.
One gallon of propane has a volume of approximately 231 cubic inches or about 0.1337 cubic feet.
One liter of liquid propane is equivalent to approximately 0.0353 cubic feet.
It is approx 1,463,776 Imperial gallons.
There are approximately 4.24 cubic feet in a 20 gallon propane tank.
Propane has a density of about 4.2 pounds per gallon. So, 17 pounds of propane would be approximately 4.05 gallons. Since 1 gallon is equivalent to 0.133681 cubic feet, 17 pounds of propane would be roughly 0.54 cubic feet.
One cubic foot of propane is roughly equivalent to 0.037 gallons. Therefore, 90 cubic feet of propane would be approximately 3.33 gallons.
That would depend on it`s size or input rating. You can get the input rating off the unit nameplate and divide that # by 2500 and that will tell you how many cubic feet of propane vapor the furnace burns per hour. If you buy propane by the gallon ask your supplier how many cubic feet of vapor a gallon of liquid propane yields and you can figure your answer.
97 cubic feet of natural gas will make 1 liquid gallon.
There are approximately 36.38 cubic feet in one gallon of liquid propane (LP) gas at standard temperature and pressure.
To convert cubic feet to gallons of propane, you first need to know the specific gravity of propane. On average, the specific gravity of propane is around 0.504. Therefore, 1400 cubic feet of propane would be approximately 702 gallons (1400 cubic feet / 7.48 gallons per cubic foot).
