"Following the death of Hans Bethe last year, I have proposed a new unit called the bethe, where 1 B is 1051 ergs or 1044 J. This would replace the unit of 1051 ergs, which is commonly used by those studying supernovae – a field in which Bethe worked. Ian Mills, president of the consultative committee on units of the International Committee for Weights and Measures, has concurred and agreed that the bethe can be used." Stephen Weinberg (2006).
