The Stefan-Boltzmann law formula is as follows, it is applied in numerous examples in radiation and can be easily calculated and derived:

, where:

= Stefan-Boltzmann Constant (W/(K^{4}*m^{2}))

, where:

j^{*} = Radiant Flux (W/m^{2})

= Stefan-Boltzmann Constant (W/(m^{2}*K))

T = Temperature (K)

Wien's displacement constant for a black body (b), which originates from Wien's displacement law, is defined as below. Note the SI units of the constant (m*K, where K is the color temperature)

, where:

b = Wien's displacement constant (m*K)

Wien's displacement equation is derived and calculated to the below (b/T) for a black body. Note the SI units of the constant (m*K, where K is the color temperature):

, where:

= Wavelength of peak emmission for a black body (m)

b = Wien's displacement constant (m*K)

T = Temperature of Body (K) - Color Temperature
