The average is about 20,000 BTU's per pound at standard temperature and pressure.
Specifically 1013.2 btu per standard cubic foot, for pure methane.

1 scf = 1 standard cubic foot 1 scf is the volume of gas at STP STP = Standard Temperature and Pressure STP (USA system of units) Standard Temperature = 60 degrees Fahrenheit Standard Pressure = 1 atmosphere at sea level = 14.696 pounds per square inch absolute The energy content of 1 scf natural gas = 1020 BTU (British Thermal Units)
The energy content of natural gas is typically measured in cubic feet (cf) in the United States and in cubic meters (Nm3) in other countries. One cubic foot of natural gas produces approximately 1,000 BTU (British Thermal Units) of energy. Therefore, 1 Nm3 of natural gas is roughly equivalent to 35,315 BTU.
There are approximately 37,000 BTU in one liter of crude oil.
btu of natural gas to btu of propane
93,000 B.T.U. per U.S. gallon 3.78 liters per gallon- 93,000 divided by 3.78 =24,603 24,603 B.T.U.'s per liter of propane
The average is about 20,000 BTU's per pound at standard temperature and pressure.

102,000 BTU = 1 ccf
How hot and how fast? 5,000 btu's will heat it. Not very hot and it will take forever. If you are using it for residential hot water application. Roughly 40,000 BTU's
The average heating value of heating oil is around 138,500 Btu per gallon. Since there are approximately 3.785 liters in a gallon, one liter of heating oil would contain about 36,600 Btu.
Ther are 1,050 BTU in one cubic foot of natural gas.
