Å·K λ_max = -------------------- = ------------------- T T/10**4 and 2897.771955 ... μm·K (2897.771955 ...)*10**4 Å·K T = -------------------- = --------------------------- , λ_max λ_maxwhere wavelength λ_max is in microns (μm) for the first versions and angstroms (Å) for the second versions, and the Wien's law constant (with ellipsis ... to show the value is an exact irrational number) is from CODATA: Fundamental Physical Constants --- Complete Listing.
Compact forms are Wien's law λ_max = 2897.7729(17) μm·K/T = 2.8977729(17) Å·K/(T/10**7) = (1/4.96511423 ...)*(hc/k)/T and Wien's law inverse T = 2897.7729(17) μm·K/λ_max = 2.8977729(17)*10**7 Å·K/λ_max.
