btu of natural gas to btu of propane
Propane = 91,600 btu per gallon
One gallon of liquid propane contains about 91,500 BTUs (British Thermal Units) of energy.
Burning 1 standard cubic foot of propane produces approximately 2,500 BTU. Therefore, burning 92000 BTU worth of propane would equal approximately 36.8 standard cubic feet of propane. The temperature produced would depend on how efficiently the propane is burned and any heat loss to the surroundings.
The conversion factor of 1 BTU = 0.293 watts. So, 60,000 * 0.293 watts = 17,580 watts. 17580 watts are required to run a craftsman 60,000 btu propane forced air heater.
Converting propane gas to liquid propane is a state change, not a chemical one. Therefore there is no loss of BTU/liter generated when it is burned.
On average, a 45,000 BTU furnace will consume about 0.046 gallons of propane per hour when running. Therefore, 1 gallon of propane should last for around 21.7 hours of continuous operation for a 45,000 BTU furnace.
propane has 21,548 BTU per pound so about 2 1/2 pounds per hour remember that propane is stored in a liquid and you need a big enough tank to allow the propane to change from a liquid to gas.
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
The "Mr. Heater F232000 MH9BX Buddy" portable propane heater has one of the highest BTU outputs for a portable heater, at 9,000 BTUs. If you need even more heat output, industrial propane heaters can go up to 400,000 BTUs or more for larger spaces.
20 LBS OF PROPANE WILL PRODUCE APPROX. 36,000 BTU @ 0 DEGRESS, 51,000 @ 20 DEGREES.
No, the BTU (British Thermal Unit) rating of propane is a measure of its energy content and remains constant regardless of ambient temperature. However, the efficiency of propane appliances may vary with temperature due to factors like combustion efficiency or heat loss.
