Gas consumption is calculated using a calorific value of MJ/m3 (1038 Btu/ft3) gross or MJ/m3 (935 Btu/ft3) nettTo obtain the gas consumption at a different calorific value:a. For l/s - divide the gross heat input (kW) by the gross of the gas (MJ/m3)b. For Btu/h - multiply the gross heat input (kW) by For ft3/h - divide the gross heat input (Btu/h) by the gross of the gas (Btu/ft3) d.
