Definition:Stefan-Boltzmann Constant

Definition
The Stefan-Boltzmann constant is the constant of proportion that defines the intensity of the thermal radiation emitted by a body in terms of that body's temperature:


 * $\sigma := \dfrac {2 \pi^5 k^4} {15 c^2 h^3}$

where:
 * $k$ is Boltzmann's constant
 * $c$ is the speed of light
 * $h$ is Planck's constant.
