COD, methane, biogas and energy converter

Converter between COD, methane and biogas in various units, with indicative energy potential (heat and electricity).

COD, methane, biogas and energy converter

This calculator converts organic load expressed as COD or methane/biogas into various units (mg, g, kg, mol, Nm³) and estimates the theoretical energy potential (heat and electricity). Results are indicative and based on simple stoichiometry of complete methane oxidation.
