Paper Abstract

Through the years, astronomers have accumulated units and nomenclature that they understand and promulgate, but that are not understood by most engineers and some physicists. For example, astronomers use the term Jansky in place of the former "flux unit," which they define as 10-26 W/m2 Hz. The steps in converting to spectral areance [flux density] in watts/cm2 μm or watts/cm2 cm-1 are described later. Other terms, which engineers should know, and their units are given in the Nomenclature.
