How to convert the combustion energy of natural gas from cubic feet to kilowatt-hours?
The specific heat of combustion of natural gas ranges from 0.2265 to 0.3398 kWh per 1 ft3 of natural gas. Depends on the composition of natural gas and the conditions of its combustion (temperature, pressure, etc.)
0,2265 kWh ≤ 1 ft3 ≤ 0,3398 kWh
