In the case of natural gas the ratio of HHV to LHV is approximately 1.108:1. The British Thermal Unit, or BTU, is a unit of measurement for heat energy. How the calorific value (CV) of gas is calculated and how we determine the amount of energy transported by shippers and suppliers, which is used to bill gas consumers. This gives you the molar heat of combustion, which is then multiplied by the molar mass of the fuel to give you the heating value. The LHV, or lower heating value, takes into account the fact that some of the heat from combustion is used to vaporize water in the fuel. This can be expressed in British thermal units (BTUs) or in calories. to calculate the btu at one of the base conditions below, multiply by factor desired base factor 14.735-60-dry 1.o177 14.73-60-saturated 0.9996 This site may use cookies.
