Widget - Unit Converter

This widget allows you to rapidly convert between popular spectroscopic units (energy, wavelength, wavenumber, frequency, and time). It also allows you to visualize the corresponding color as it will appear.

Help

• Enter a value in any box and the converter will automatically convert to other units.
• ↑ : Indicates the corresponding light color as it will appear to your eye. The color values are an approximation. The colors fade on either end of as the wavelengths move beyond the visible range.
