Natural gas is mostly methane (CH4), but it also contains small amounts of other gases like ethane (C2H6), propane (C3H8), butane (C4H10), and pentanes (C5H12). This value is the higher heating value (HHV). Higher Heating Values mean that more energy can be extracted from a given quantity of natural gas, and this usually results in a higher price for the gas. If you already know the HHV and composition of your fuel I would apply the following: LHV = HHV - Lv_H2O (H2O_content_w + 9*H_content_w) [MJ/kg] where Lv_H2O = 2.441 MJ/kg 9 is the amount of water.
