Recent analysis of relativistically expanding shells of cosmological {gamma}-ray bursts has shown that if the bursts are cosmological, then most likely total energy (E{sub 0}) is standard and not peak luminosity (L{sub 0}). Assuming a flat Friedmann cosmology (q{sub 0}=1/2, {lambda}=0) and constant rate density ({rho}{sub 0}) of bursting sources, we fit a standard candle energy to a uniformly selected log N-logS in the BATSE 3B catalog correcting for fluence efficiency and averaging over 48 observed spectral shapes. We find the data consistent with E{sub 0}=7.3{sub {minus}1.0}{sup +0.7}{times}10{sup 51} ergs and discuss implications of this energy for cosmological models of {gamma}-ray bursts. {copyright} {ital 1996 American Institute of Physics.}
