[QUOTE="Hysteresis]So My error was the assumption that my old meter was calibrated in cu ft due to its age and as the new meters indicated as M3 it seemed incorrect that the new supplier would use the same conversion numbers as my old meters.[/QUOTE]
It's good to hear that you have resolved your problem; but you are wrong in thinking that the old meter must have been indicating cubic metres as it was using the same conversion of 39.5 MJ per m3. The old meter could have been indicating 100's of cubic feet which is then converted to cubic metres by multiplying it by 2.83; i.e. a meter reading of 1(00) cubic feet = 2.83 m³. The reason for this conversion is that, by law - see my last post, the thermal energy of gas must be quoted in MJ per m³.
