The Korean standard for judging the gas interchangeability of domestic gas equipment is Wobbe Index, which determines not only the performance, efficiency or safety of gas equipment when existing fuel is replaced with some other fuel, but also if the new fuel can replace the existing gas without increasing gas emissions that negatively influence the environment (Wobbe Index = specific gravity /√ calorie)

• Range of the Wobbe Index (WI)
