A more useful indication of the strength of an explosive is the relative effective energy. Relative weight effective energy (RWEE). RWEE is defined as the effective energy of an explosive compared to the effective energy of an equal weight of standard ANFO (i.e. 94% AN, 6% FO, density = 0.8 g/cm 3).
