Conversions between photon fluxes, energy fluxes and magnitudes are described in Section 1 for continuum units and Section 2 for line-emission units. Various other unit conversions are given in Section 3: astronomical units to SI units (Table 4); units and names relating to the electromagnetic spectrum (Table 5), and; SI prefixes (Table 6).
