C1 equivalent

Term · Environment · MLC-T-ENV-003895

Convention of expressing HC concentrations based on the total number of carbon atoms present, such that the C1 equivalent of a molar HC concentration equals the molar concentration multiplied by the mean number of carbon atoms in each HC molecule. For example, the C1 equivalent of 10 µmol/mol of propane (C3H8) is 30 µmol/mol. C1 equivalent molar values may be denoted as “ppmC” in the standard-setting part.
