What is the exact difference between GCV & NCV? - Quora

Gross & Net Calorific Values Gross CVor 'higher heating value' (HHV) is the CV under laboratory conditions. Net CVor 'lower heating value' (LHV) is the useful calorific value in boiler plant. The difference is essentially the latent heat of the water vapour produced. Conversions – Units From kcal/kg to MJ/kg multiply kcal/kg by 0.004187
