Depends on the size of the burner, if the unit is 5000 btu's ,( probably much smaller), but it makes the math easy that would run a fridge (full throttle) for 20 hours. The flame cycles, so it won't use that non stop. To make it easy., divide the amount of btu's into 93,000 (roughly the btu's in a gallon of propane) and you will have your answer
40 hours
Propane weighs 4.4 lbs per gallon, so 20 lbs of propane 4.54 gallons.
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU burner, on high heat, it will last a bit over 4 and half hours of run time.
Kilowatts are really a measure of power, that is, the rate at which energy is being used. It depends on how big your engine is. You could have a tiny, low-powered engine which uses the gasoline up very slowly,or you could have a huge, high-powered gas-guzzling monster, which would use it up fast. What you really might be asking, however, is "what is energy content of a gallon of propane?". Energy is measured in Joules. A joule of energy will keep a 1 Watt engine running for 1 second. If you ask: "How many kilowatt-hours of energy can an engine get out of a gallon of propane?", that would depend on the efficiency of the engine, which could be as low as a few percent. Wikipedia states: "When properly combusted, propane produces about 50 MJ/kg"

Too broad a question. Need BTUs of heater + how many hours running per day to answer.
1 pound of propane is a little less than 1/4 of a gallon.
It is approx 1,463,776 Imperial gallons.

According to the Wikipedia entry for propane, liquid propane has thermal energy 91,600 BTU per gallon. So 1 therm which is 100,000 BTU will correspond to 100,000/91,600 gallons, result = 1.092 gallons.
That depends on the output level of the propane.
3,366.23 cubic feet.
Propane weighs about 4.2 pounds per US gallon, at 60 degrees Fahrenheit. Propane expands 1.5% per 10 degrees F.answered by Special:ContributionsSo you take 4.2 * 47 = about 197.4
It lasts around 10-12 hours on a 20lb propane tank.
30. You just said it's a 30 gallon tank.
Mine holds 127 gallons of propane when filled up to the 80% make, the fullest they can get.
