WebEmissivity is defined as the ratio of the energy radiated from a material's surface to that radiated from a perfect emitter, known as a blackbody, at the same temperature and wavelength and under the same viewing conditions. It is a dimensionless number between 0 (for a perfect reflector) and 1 (for a perfect emitter). WebEmissivity then, is a fractional representation of the amount of energy from some material vs. the energy that would come from a blackbody at the same temperature.
