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.
90 cubic feet equates to 673.24675 US gallons of liquid propane.
one pound of liquid propane equals 8.5 cubic feet of burnable gas will this help
It is approx 1,463,776 Imperial gallons.
1 cubic foot = 7.48 US gallons. Using the factor-label conversion method: 20 gallons x 1 cubic foot/7.48 gallons = 2.67 cubic feet
97 cubic feet of natural gas will make 1 liquid gallon.
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.
1 cubic foot = 7.48 US gallons
1,400 cubic feet per hour of liquid propane is about 10,472.7 US gallons per hour.
1 cubic foot of liquid oxygen is about 860 cubic feet of gaseous oxygen.
Just doing some research on conversion myself and found the following resource which was helpfulhttp://www.ct.gov/drs/cwp/view.asp?A=1511&Q=267170basicallyCOMPRESSED PROPANE (GASEOUS FORM) EQUIVALENCY INFORMATION: At 14.73 lbs. of pressure per square inch (psi) and 60 degrees Fahrenheit: * 1 cubic foot propane = 0.0278 gallons propane * 100 cubic feet propane = 2.78 gallons propane * 1 gallon propane = 35.97 cubic feet propane * 100 gallons propane = 3597 cubic feet propane Hope this helps
