Photon conversion calculator

Including the common units for IR, visible, UV, and X-ray.

(To use: Type a number into a box in the second row, then click outside the box or press the "Tab" key. Repeat.)

Notes: "K" is kelvin, calculated by "temperature = (photon energy)/(Boltzmann constant)". This temperature is a factor of ~ 5 larger than the temperature of the blackbody radiation spectrum with the given peak wavelength. ("Wien's displacement law".) All other units should be self-explanatory.
