See http://hyperphysics.phyastr.gsu.edu...mo/stefan.html
also http://hyperphysics.phyastr.gsu.edu...tefan2.html#c1 for the value of this constant expressed in terms of other fundamental constants. Because the StefanBoltzman law is a flat spacetime law, it's not entirely clear to me how to apply it to black holes without some thought.
