See http://hyperphysics.phy-astr.gsu.edu...mo/stefan.html

also

http://hyperphysics.phy-astr.gsu.edu...tefan2.html#c1

for the value of this constant expressed in terms of other fundamental constants.

Because the Stefan-Boltzman law is a flat space-time law, it's not entirely clear to me how to apply it to black holes without some thought.
