How many kW energy is in 1 liter gasoline?

In the US Natural Gas output is measured in cubic feet, First you must convert feet to meters: 3.28084 fpm, then we must determine cubic feet per cubic meter, 3.28084 X 3.28084 X 3.28084 = 21.528 cubic ft in a cubic meter and since there are 1000 btu in a cubic foot of Natural Gas 21.528 x 1000 btu = 21,528 btu/cmtr. Then you must convert kWh to btu. 1kWh=3413 btu, so 21528 btu divided by 3413 btu = 6.307 kWh in a cubic meter of NG: so 1 cubic meter divided by 6.307= 0.1585 cubic meters of NG = 1 kWh. Of course these are output ratings not input. So depending on the efficiency rating of the NG furnace being used one would need to add the heat that is lost up the chimney or the inefficiency rating for an accurate answer. For example with an 80% efficient gas furnace one would need to add 20% or 0.032 to the 0.1585 cubic meter value we got earlier to allow for waste and the answer is actually 0.1905 cubic meters total input of NG needed per kWh produced. I hope this is right... End -H2045
