What is the calorific value of cng fuel?

The calorific value of compressed natural gas (CNG) is typically around 35 to 40 megajoules per cubic meter (MJ/m³) or approximately 900 to 1,100 British thermal units (BTU) per cubic foot. This value can vary based on the composition of the gas, primarily its methane content. CNG is considered an efficient fuel due to its high energy content and lower emissions compared to other fossil fuels.
